A whipped bitch with actions deeply synonymous with the actions of a loyal, terminally-ill pet. Usually found to have a woodland critter for hair. Will tell you how much he cares about his consistently failed crush. In response, you will most likely blow him off and inform him that he is a fucktard.
Generally spotted with an imaginary spiked collar with a short leash made of chain links attached to it. On the other end of the collar lies an emotionally mutilated girl who doesn't know what the fuck she wants. Quite often, this girl can be categorized as a thunderbunt.
