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!!!"
