Bumbitch 

A female usually of lower class in which uses people to her benefit with no gain to others. She adapts to situations according to her wants. "Wants" because Bumbitchs always want because they never have. Uses the looks she hasn't already wore out to her advantage when using others. Lord knows she can't use her brain. Also brags about the children she never raised and is known to live couch to couch.
Bumbitchs are also people pleasers with high aspirations of becoming the first female version of El Chapo.

I'm tired of these Bumbitchs taking my belongings but leaving stds.
