Mostly men use it because they don't care for the respect of their female counter parts, but women just as idiotically and without reason use it.
Smart One: Bitches? That's how you refer to women?
Dumbass: Yeah. They don't deserve no respect, yo!
A typical bitch cares a lot about how she looks, and doesn’t give a crap about anyone, who isn't at her level (such as good looks, social skills, etc. Anything. One that is lower than her expectations.
Most have a sassy attitude, and like to match up to others and see that they are better then anyone else (Except their friendly, usually). The often bully those who are considered a lower standard then they are (usually girls). Not all bitches are bullies. Many just don't care.
They party every weekend, get drunk and do drugs.
Some bitches care more about themselves, and their friends, such as good grades, future goals, etc. Not all bitches are the same.
