look up any word, like fleek:
 
1.
cock loaf: when a man or boy takes a nice warm freshly baked loaf of bread and starts to hump it for pleasure, maybe slapping on some butter for lubricant.
cock loaf: referring to someone as being a loser pretty much, I would think that if anyone screwed a loaf of bread they would be a loser, it is basically an insult.
Jim says, "fuck you asshole", then Brad says, "no fuck you, you fuckin cock loaf". Then Jim walks away with his head down and a sad, bitch ass, whiney suck-a-titty baby look on his face.
