An affliction, typically of post-pubescent males, whereby sebaceous glands in a region of the body become overactive once nearby skin is shaved with a razor. Affected regions of the body are typically the neck and near the mouth and jaw, though people who shave their chest or anus or pubic regions may experience razor acne in these regions as well.
I downloaded a shitty porn. The guy had razor acne all over his browneye and gooch, and they kept showing closeups. It was nadsty. As in, he shoulda used Nads.
