paingasm
A super strong orgasm you get when someone hits you in the crotch so hard it feels like your nuts are about to explode.
My uncle kicked me in the balls and I had a paingasm so strong I cried like a baby.
She slammed my face into the pavement and I got a paingasm that made me yell 'MOMMY!'
He pulled my hair so hard I felt a paingasm in my head and my crotch at the same time.
