knuckle babies

The man custard that shoots from the penis when rubbing one out.

"That chick is so hot, when I get home I'm gonna pop off some knuckle babies. When doing so, she will tell me I am great, and I will believe her."

knucklebabies

Sperm or semen, especially when induced by masturbation.

"Yo Scooter, what's up with your petrified Kleenex?"

"It's nothin' dude, just my knucklebabies from rubbing one out earlier today."
