I wanna kick his a**!

My friend's boyfriend was being a complete a** and I want to kick him where it hurts. Damn! You don't mess with my friends b**ch! He was mad at her because she didn't text or call him to see if he was ok just because he wasn't in school for 2 days. And then he was posting mean things on her wall and his own wall. Then his friend got into it and was posting bullshit on her wall saying stuff like "you don't deserve him" and that she was a f**king b**ch. And then bf's sister got in and was saying that my friend was a grinny b**ch. What does grinny even mean?! He should go to he**. (h.e.double hockey stick)
