Fapping as fast as you can, when your hand accidentally slips off the rails and you punch yourself in the crotch, thus demolishing your nutsack. May result in bruising and/or infertility.
girl 1 "what are you doing tonight?"
girl 2 "I dunno. My bf pissed me off so I might go home and faphammer him..."

"I faphammered myself so hard last night, I think I ruptured a testy."

Girl "I hear you like it rough"
Boy " yeah, faphammer me."

"I would rather faphammer myself, than listen to one direction."

"faphammering yourself really is an erection rejection."
