scrotdrum

The musical instrument created by stretching the skin between the testicles. Especially effective in warm climates.

Also: scrotdrumming, to play the scrotdrum.

She wailed away on my scrotdrum last night with some pretty wicked beats.

The drumroll on the scrotdrum reverberated through the auditorium.

scrotdrumming

Repeatedly slapping your nut sac against your leg.

Jimmy was bored in class so he stood up and started scrotdrumming.
