A type of legless, tight underwear. On e621, the tag refers to the style traditionally worn by males, and not, for example, women's briefs.

Some briefs have a two-part front with an opening designed to slip the penis through for quick urination (as opposed to pulling it over the top). Most are apparently tight enough to make this nearly impossible without urinating on one's leg.
