beating penis

Rough, borderline abusive male masturbation (self or otherwise).

-Misheard from Starbomb's song "Rap Battle: Ryu vs. Ken"

-Think you can stop beating penis long enough for this rap battle to the death?

-Probably!

-Why are you in the hopsital?
-I was beating penis a bit too enthusiastically, I'm checking to make sure I didn't get an infection.
