1. A bitch
, always spoiling for a fight, looking for a way to run someone else down, or taking something the wrong way. May be either gender.
2. A fast-moving bitch that will roll up behind you and smack you in the head (verbally or otherwise) without warning and for no good reason.
3. A bitch who can't stand it if he/she isn't getting all the attention
, all the time.
In any "reality TV" show, there is at least one "bitch on roller skates" who can't get along with anyone else and always has to be the center of attention.
