The act of a very addicted or chronic masturbator; getting so into masturbating, or jacking off, that the dude becomes a total goon; becomes stupid on his own cock. Can think of nothing else but busting a nut.
Big Bro: Dude, I'm sorry. I didn't know you were jacking off.

Lil Bro: I'm not JUST jacking off bro, I'm fucking gooning on this dick!
