Verb - To "fap" or "fapping".

The act of loudly thumping one's flaccid penis against one's thigh to produce a loud slapping, or "fapping" noise. You can fap against other things, like someone's face or butt cheek, or if you get really good, the back of the hand that you're actually fapping with at the same time. Foreskinless people probably can't generate the same noise.

Also, there is the "Upward Aggressive Fap", which is literally what the name would suggest. Aggressively ping your dick up against your pubic region, causing impressive acoustics, red marks to body and knob, and a painful stinging sensation.
- Hey listen to this sick fap!
- I was doing the Upward Aggressive Fap and now my cock is all red and sensitive.
- Look we're fapping in sync!
- I fapped her cock holster so bad she had a cock holster period.
