1. Leaving a party or a club early to go home and eat drunk food.
Because you know you’ll have more fun when it’s just you two and a pizza. (Maybe two pizzas.)
2. Getting drunk by yourselves and ditching the party you were meant to go to together.
Usually skipping straight to the pizza stage of the night.
3. Sharing a toilet cubicle.
There are some times when the gossip is so urgent, the conversation so deep, or the advice so necessary, that you can’t possibly stop talking in order to pee. So you must pee together.
4. Telling them your grossest story.
Usually involving some kind of bodily fluids. And when you’re done, they’ll tell you an even grosser one back.
5. Receiving an emergency phone call from them in the middle of the night.
Emergencies could be anything from they just saw their ex snogging someone else, to actually serious stuff, to they were drunk and just really missed you.
