Someone who says another person is their best friend, and when their best friend starts to like a guy...they try to steal them. Then there FORMER best friend gets mad and ditches them for another awesome person named Haley. Then the girl who tried to steal boy from "best friend" gets a new best friend, and when that friend starts to like a DIFFERENT boy...they try to steal him aswell.
