Bat-Fap

Arguably the best wank you will ever have. Introducing the bat-fap, the new masturbation technique taking the world by storm.

A bat-fap is where you hang from the ceiling by your feet like a bat and proceed to flap your wings like a bat with screeching getting louder when closing in on a climax. Use your keen sonar abilities to aim your bat load onto the hoards of unsuspecting children below.

Batman mask and crotchless pants optional but highly recommended

"Hey man, have a fap last night?"

"Yea boss I had a bat-fap"

"Yea i heard you going to town, better of worn your mask"

"Amen to that. You think I'm some sort of boner boy"

"That reminds me my uncle achieved the most brutal bat-fap yesterday, got little jimmy right on the nose"
