look up any word, like wyd:
A dirty liar who will tell you she's 13 just to sleep with you when she's really only twelve. She'll say that she loves you but really she only wants you for sex. Then she'll rip your heart out by leaving you for an older guy.
Did you get laid this weekend?
Ya, I slept with Jack's Sister!
She's just toying with you man.
She said she loved me!
She told me that to... Last weekend.
It's gonna be okay man... It's gonna be okay
