Simon~ he gets awfully protective when he's drunk. If any of the boys try to talk to you while he's drunk, it usually ends up with his mate lying on the floor. Which isn't the best. But if he drinks too much, he usually passes out as well anyway and forgets anything that happened the next morning.
JJ~ he acts wild, like that night was his last night of living. Even though he drinks tons, he always manages to keep it down him. After the crazy partying - on the way home - he bursts into an explosion of emotions. Tears streaming down his face while he tries to say a speech about how happy and grateful he is.
Ethan~ after drinking a lot, Ethan gets very sleepy so either falls asleep on you, or on the floor. That, or he pukes over himself.
Tobi~ he doesn't drink so when you go out clubbing, he just has a great time with everyone. Especially watching you getting drunk and acting foolish.
Josh~ the inner party-animal comes out when Josh is drunk and he acts mental. He has way too much to drink and usually ends up thinking one of the guys is you, in an attempt to make out with them.
Vik~ he grabs the nearest thing to a helmet and runs around the club screaming "I'M A FOOKIN 'ELMET BOI M8" everyone laughs and, when you're drunk enough, you usually join in as well.
Harry~ it takes him a while to get proper drunk, but when he does, he doesn't act too wild but he's also not the quietest. He gets very flirty when he's under the influence of alcohol as well, and we all know what that usually ends in;)
