A female or group of females who live in the wild and tend to hunt in packs. They prey on the male species and relentlessly eat your heart out of your loving chest.

They often lie, cheat, sleep with you post break up, or call to say that they are sleeping with another man. In order to survive an attack we suggest you fall to the ground and just hand over your wallet and sometimes in extreme cases years of your life.

Matt: So wait...she's single now?
