Nutnumbing

Causing the man's testicles to retract, so the man doesn't feel them in their original state. This will make it feel as if they are numb and/or removed.

Yeah, I saw this guy who sprayed hairspray on his dick.
- Ouch man, I can imagine the nutnumbing pain.

Neyland Nutnumber

When a girl from Tennessee sucks your balls so hard that you loose all feeling in your testicles.

This Tennessee sorority girl gave me a Neyland Nutnumber in the stall during Tennessee vs Florida halftime.
