A group of immensely cool people, who often have a few tag alongs who aren't as cool and sometimes have their own sidekicks, like ulrik, or Gandhi. The main difference between The Posse and a Posse is that anyone can be a part of a posse, where entry to The Posse is limited.
Guy 1: Dude, I'm in the posse!
Guy 2: Me too man!
Guy 3: Damnit, the posse turned me down. I always wanted myself an ulrik.
Or
Person 1 : I heard the posse are coming to america
Person 2 : Really omg!? wow imma go see them
Person 3 : i dont have a moustache so i cant go :(
Person 4 : i bought the blow up ulrik last friday
