Noun: Bitch (bich):
A miserable person who sucks all joy and happiness out of life, and makes life a little less worth living by her consistently shitty attitude. When not complaining, her drama and gossip will fill the void. He or she (but usually she) refuses to do something with a group, and will forego hanging out with said group unless they're doing something she wants to do. She will put her interest ahead of others every single time, just for the sake of being a bitch. A bitch hates fun.
