one who is friendly to you/others in your/people's presence, but will say negative things about you when your not around in a heartbeat. some people do it all the time, some just in moderation...

it's something that everyone is at least a little bit at some point in their/your life, just like hypocrites.
everyone is a backstabber, everyone is a hypocrite. almost pointless to even use these too words...

Someone that will pretend to be your friends and find out all of your secrets. Once they do that they take the most embarrassing ones and spread it just to embarrass you.
Samantha: I think I like Josh, but I know he doesn't like me back. If I told him I liked him it would ruin our friendship
Brittany: Hey Josh, Samantha likes you she wants to have your babies.
Josh: Ew, I'm not talking to her anymore.
Samantha: that bitch is such a backstabber

Someone who talks shit about you behind your back. If you were on fire and this person had a bottle of water they would rink the water and apologize about it later when you are in the ICU. This person makes you walk on hot coals to please them and then they turn around and talk about behind your back while still acting like your friends...stay away from theses people they are no good.
Good Friend: "OMG sorry i didnt mean ... is there anyway i can make it up to you?"

Bad Friend: "Nah.. it's okay it's fine, don't worry about it"

1 hour later
Bad Friend: "guess what this bitch did to me..... I have always hated her. all she wants is attention.. she should go die in a hole"

Next Day

Good Friend:" Hey Bestty"

Bad friend:"Hey Bestfriend in the world" -.-

Another person: "You do know she talks shit about you behind your back"

Good Friend: "WHAT A BACKSTABBER!!!"

People who are bitches and betray you. You should block them and tell them to never speak to you ever. They are usually popular people and are hoes. So just stay away from them.
