umm, why are my testicles moving?

cut em off.

You may have Waltz Syndrome. Have someone put their ear up to your testicles and listen closely. If they hear music, then you have Waltz Syndrome which causes the testicles to dance. Have the person yell "Stop the music in there!" That usually does the trick.

Otherwise, a good hard kick to the groin may stop them from dancing for years.

Bravo.

This is just proof that mens' privates all have a mind of their own, but unfortunately no mouth. Perhaps your testicles are trying to tell you something using testicles gestures. Lmao
