Similar to butt cheeks, but formed with your ballsack. This word describes the shape your ballsack makes when both balls are perfectly aligned to create a "butt cheek" shape, except this is with your balls, so they are called ball cheeks. Could also be used as an adjective to describe something that is bad (an insult). *Similar to ass cheeks or cheeks.
"Dude, your ball cheeks are showing" or "Dude, you're so bad at 2k... you're ball cheeks"
