Dick Knuckle is when during an erection your penis is bent too far back or forwards and makes a loud pop.
Roxxy was riding my fat cock and leaned too far forward and I got a serious dick knuckle, OUCH!

While masturbating I decided to press down on my penis and I totally gave myself a dick knuckle!
