look up any word, like sparkle pony:

Dude she is a boy stealer!

A girl that goes behind her friends back and flirts a guy her friend told her she likes. She manipulates the guy to like her back and makes it as obvious ad possible to her friend.
Friend: Hey do you still like that kid you met on vacation?

Me: Yeah but I saw Anna's phone and saw that she's been texting her for months. I can't.

Friend: Ugh she is SUCH a boy stealer!
