1. Go on a mates holiday
We say it in every feature we write like this and yet it will always be relevant. Going on a mates holiday will be the most fun you can have with your clothes on (clothes not required), even if it means stretching your budget to get there. Chuck a tenner in a savings account every week for a few months, grab your swimming stuff and your BFFs and get a plane to anywhere that promises sunshine and cocktails. DO IT.
2. Live together
Anybody who's ever lived with their mates will tell you there's nothing more satisfying than coming home from a shit day at work to your BFFs and a takeaway pizza. Living together is great for the bad times, good times, drunken times, hungover times.. have we made our point? Good.
3. Talk about sex
There's such an unnecessary stigma surrounding talking about sex in this country (but that's another matter), and so if there's anyone you can discuss your experiences with, it's your best friends. Talk about vaginas, willies, technique, positions - share your knowledge and gain in return! It's empowering and important.
4.Laugh about people you used to know
Real talk: there is nothing more satisfying than Facebook-stalking people you used to know, idolise and essentially be jealous about every aspect of their life, only to find out their lives haven't really moved on for the better in a way yours has.
(Side note: Yes yes I know this sounds awful and I wish them all the best, but we're all guilty of envying others - especially at school - so it's nice to know years on that what I thought was 'the perfect life' isn't all it's cracked up to be.)
5. Drink expensive cocktails
Whether you make a special trip to a specific city to drink cocktails with a great view or just find a local bar that makes a kick ass mojito, round up your mates and drink ALL the cocktails together. Y'know, the q expensive ones that come with fancy aperitifs and makes you feel really, really classy? Yeah, those.
6. Drink cheap alcohol
Similarly, there's something super satisfying about finding a pub that sells a glass of vino for a pound cheaper than the one next door, or sitting in a park drinking cider from a can that you bought for 90p from the corner shop. The best memories are made on evenings like this, and you only have to reminisce about summer's gone by with your pals to remember.
7. Cry and have a pity party
Even when everything in your job/life/love departments seem to be going your way, there's nothing wrong with wanting a big old cry and a bit of a pity party - and who better to spend it with then your friends and two important men called Ben & Jerry? Have a big love in, talk about feelings and lame shit and don't be embarrassed about a single thing.
8. Have sleepovers
Adult life is great for lots of things, but the absence of sleepovers with your BFFs is not one of them. Face masks, midnight snacks and a whole load of rom coms will never not be appealing, especially if the impending tube journey home doesn't have to happen until the morning after.
9. Host dinner parties
From experience, the best bits of nights out are usually before you even get to the bar. Whack a fish pie in the oven, ask your mates to bring a dish/bottle and host the night away - even if it turns out a la Bridget Jones.
10. Share music
Even if you could think of nothing worse than listening to the Top 40 and it's their absolute favourite, sharing songs is an important way to share even more of your likes and dislikes - even if you have to pretend to like Sean Paul for an hour or two*.
*Scrap that, everyone should always like Sean Paul.
11. Help each other through heartbreak
A shitty yet inevitable part of your twenties is getting your heart broken, and no matter how strong/independent/fabulous you are, it's a nightmare. Which is why the #squad will - and should - be there at 4 in the morning when you 're having a meltdown, Four Weddings and a Funeral DVD in tow.
12. Buy outrageous things together
No no, we don't mean a pet monkey that neither of you are going to look after, but if your best friend is looking for someone to tell them buying the ridiculously OTT bag is a great investment, be that person. Even if LOLing about how hideous it was years later is all you gain from it, still a good story, eh?
13. Take photographs
And not the triple-filtered-500-attempts ones for Instagram, but the ones you save secretly on your phone to laugh at when you're sad. The hungover/drunk/food all around your mouth ones that aren't really appropriate for anyone bar each other. We know you've all got them on your camera roll. Don't lie.
14. Get to know each other's families
One of the great things that comes with having best friends is the prospect of gaining a second family in their home, so take the time and effort to get to know their siblings and parents. If anything, it just means you've just got another set of helping hands when it comes to doing really adult-y things like building shelves or getting your car insured. Ahem.
15. Road trip
Mainly because you can make a driving playlist and pretend to be in a music video whilst Beyonce blares out of the speakers in your Fiat 500 (or equivalent), a road trip is a MUST with your BFFs in your twenties.
16. Have each other's backs
An obvious one when it comes to your best pals, but there is nothing more comforting and reassuring when you're having a bad time on the job/family/dating front than your best mates having your back. Whether that comes in moral support on social media, unfaltering honesty or snacks.
17. Meet new people together
Having a close set of good friends is great, but d'ya know what's even better? Meeting new people when you're with your mates, so no one has to go through that 'best friend jealous' thing we all secretly get. Plus, it takes away the daunting prospect of making a bad first impression as an individual - you can do it together instead.
18. Go to gigs and karaoke
A fact: Karaoke - in it's purest form? In the shower. In its equally great form? In a dedicated booth - will never not be GREAT.
A lie: Your 'Single Ladies' rendition is 1000x better than Queen Bey's.
19. Shout about your friendship
Oi, you. Yeah, you. I'm guessing if you've made it this far down this feature you've got a great best friend, right? So LET THEM KNOW. Write little posts about it on Facebook, share hilarious throwbacks on Instagram and also ACTUALLY TELL THEM FACE TO FACE. And not when you're drunk in a toilet and one of you is about to throw up.
20. Empower each other
"Here's to strong women. May we know them. May we raise them. May we be them."
