Dude,if your going to use my ball gyroscope at least clean it and put it back in my wig drawer.

Dude I was in class and my ball gyroscope fell outa my gym bag! I was so embarrassed!

"My ball gyroscope got caught in my ass pupes man!" "No way dude that's sick" "Yea I know, I gotta do some serious manscaping"

My balls got stuck in the ball gyroscope so long they lost circulation and fell off.
