prickly ball

Is when someone shaves their gentalia once and let's the stubble grow in and doesn't shave again, making sex "prickly".

People who are a prickly ball is extremely uncomfortable to be around.

For example:

"Last night I had sex with Tom Ferris and he totally has a prickly ball."
Or

"Dude, I hate that fucking Tom Ferris kid. He is such a prickly ball!!"
