1 definition by Coach Mike K
A sexual position that is best performed in a bathroom stall. The receiving partner is bent over the toilet while the giver is positioned directly behind. At the point of climax, the giver dunks their partner's head in the toilet and gives it a flush while simultaneously pulling out and ejaculating in a circle around the anus aka the donut hole. The end result is the dunkin' donut.
