Crush-crazy cracker
You know the type--

Crazy white boys who think they're in love after sleeping with a chic one time. Then don't leave her alone, start texting, calling, showing up at her house all the time. They think they're so in love that they start rearranging their life and future plans in order to be near this chic, who by the way, isn't into him because he's a CRAZY loser!!!
"That guy from the other night turned out to be a crush-crazy cracker! He won't stop texting me. He calls me 20 times a day to tell me how much he likes me. He even said he was moving here and taking a new job so we can be closer. Girl, I don't even like him!"
