A particularly bushy, dense goatee, in the shape of a circle around the guy's mouth. So-called because it resembles a chocolate frosted doughnut. Popular with frat boys (goes well with a cinched brimmed baseball cap) and baseball players.
Kevin Youkilis of the Red Sox shaved off his mouth donut for charity.
