a person, usually a guy but not limited to them that for
whatever reason doesn't want
other people to be
successful, usually with girls but not limited to them and therefore, hates on you.
1.) you could be at a bar talking to the best looking girl in the joint, and this girl might be all about you too, but then your drunk buddy who happens to be a hater rolls up on the scene and starts falling all over the place, making
you look like an asshole and scaring her away. That's a hater.
2.) you might be in a bedroom with a girl about to get a piece and then all of the sudden, your buddy starts banging away at the door for no reason. He just wants to figure out a way for it be as hard as possible for you to get some. That's a hater.
3.) the worst kind of hater though is the one who talks bad about
whatever it is you're doing, but only when he's not involved himself. when he's part of it,
it's all good, but when he's not doing what you're doing, don't be surprised if he's talking bad about it to everybody else.
