Top definition
The act of applying pressure to the perineum (the area between the scrotum and the anus) on a man during sexual activity. "It taint your balls, and it taint your ass!" Best when used during oral sex, or a hand job firmly stimulate the prostate gland which is located there...causing an INTESE ORGASM! Go POP YOUR TAINT, GUYS! Can also be done while masturbating, or having intercourse. Fun for all occasions!
You're not getting out of this bed without a little taintpopping, my sweet!
