When someone acts like a close friend and then goes and talks about you behind your back calling, you a slut and a whore, or a bitch, sometimes things even worst
it happened to me this year, my best friend or at least who I thought all of a sudden started calling me a whore and a bitch, so I stopped hanging out with her she becam e a big fucking bitchy backstabber

buttholes, jerks, mean people, people who you should drop instantly they will never be able to trust, people who you think are your friends but are only going to 'stab you in the back'.

A backstabber is usually someone who doesnt care enough about you as a person to treat you decently. They often become bitchy after earning your trust. It always ends up kicking you in the ass when you try and befriend one of these snakes. You gotta be careful what you say, because they might turn your own words into the knife that they will use on you later!
X: I can't believe she did this too me!
Y: Who?
X: *points to Z* Her.
Y: Yeah, you gotta be careful around that bitch, she is a backstabber.

backstabber, a person pretening to care about you but causes you downfall in future.
For example:

backstabber: No problem friend!

------ 5 days later -------

backstabber: I always hated you annie!
annie: but you said we were friends...
