The loud slap you get when your nuts bonk your palm like a stupid kid during a solo session.

My jack taps woke up the whole neighborhood. I was so loud I think my mom called the cops.

Jack taps at 3 a. m., my roommate asked if I was being tortured.

I tried to be quiet, but my jack taps sounded like a donkey in a blender.
