look up any word, like blumpkin:
An individual that realizes, typically in his formative years, that the insecurity he has strugled with his whole life is actually latent homosexuality. This type of homosexuality is often a catalytic, rebelous response to an "overbearing" parent/parent figure; whom trys to re-live their dreams of playing in the NFL through their children. Grimebob's often become infatuated with blumpkins.
When it occured to Magnus that he would never beat Wes Welker in a foot race, he realized he was nothing more than a Grimebob
