bick

To shave your head (or other body part) down to the skin so that no hair or only a little stubble remains.

From the razor brand name bic. The 'k' is added to clarify pronunciation in a written format.

I've bicked my head three times, but now I just let it grow.

Vin bicks all over because he doesn't like body hair.

Don't use clippers, just bick in the shower, it's faster.
