1. Using a person as your friend but actually really hating their guts.
2. Using a person as your friend, and then ditching them for new friends.
"Oh my god, that girl such a backstabber!" She said.

A backstabber is a friend who says she will be there for you and look out for you not 2 worry .. She continues the act and then 1 day when you and ur boyfriend break upo she confesses 2 him she has a crush on him ..
Martha is the biggest backstabber of life
