sluts
The word actually has several meanings, the most commonly used one being that the girl is mean/cruel...
Bitches
It is also commonly used instead of the word girl/woman by gross people :)
It can also mean being someones bitch as in doing everything someone tells them to do etc...bitch also is the term for the female dog, but I don't think people really use that anymore..
last but not least it can also be a verb, to bitch which means to whine and complain about things...which of course can lead to the word bitch referring to someone who complains a lot.
I really hope this has been educative for some people, it was a pleasure for me anyway...
