The act of ejaculation or masturbation. Rooted from the trifecta of knuckles that surrounds the end of a penis during masturbation.
"Hey man I'll be over in like 5. Just gotta go knuckle-off a few."
"That girl was such a tease, but whatever. I'll just knuckle-off a few when I get home."

Close to the idea of a moose knuckle or a camel toe. The only difference is that the woman is really fat and she wears tight pants and you can see the cellulite through them, looking very similar to a sponge.
I was walking down main on a Friday night. Bitch had white yoga pants on and you could totally see her sponge knuckle.
