a
gurl is sat on her own that doesnt have the best style or something like that another
gurl comes past with a group of friends and they are being bitchy and 1 of them says "what a skank bitch" then goes back to the conversation she had before.
It is also used in different terms e.g skank whore, skank hoe e.t.c. then those terms are used when in a
bitchin fight.
