the small bag lining a bin inside a stall in a women's bathroom that gets filled up with tampons and rum bottles over the course of a day

A person who is so annoying that you would rather be bitch slapped in the scrotum than have a conversation with them.

-When someone is a literal sack full of bitchness

-A very offensive thing to call someone when they wont stop being a lil bitch
Girl: OMG, why can't you be more like him?! why don't you buy me stuff and give me the things I ask for?!

Guy: Holy crap.... can you please shut up and stop being such a bitch sack?
