Gibbies are like hypies. You know.. when you are really, really hyper or excited? I guess the single form of "gibbies" is "gibby." If you got a high score on a video game or something.. and you were kind of expecting it, and you - with out emotion - are like, "YES." ....thats a gibby. But if you HAVE the gibbies usually you have more than one. :) I'VE GOT THE GIBBIES RIGHT NOW!

A Gibby is a chubby rich boy that hates peasants. He only wears Gucci, Lv, Supreme and other high end designer brands. He makes fun of the less fortunate.
