Level-3 sex move where you lay a donut on your girl but hole and fuck the shot out of it, until you cum. Using your cum as frosting, you then let your girl squeeze it out and eat it.
Me and the girl from the bar had donut holes last night
When a person took such a fat shit that it only touches the outside rim of their asshole. Leaving a milk mustache effect on the anus. Only to be discovered when hitting it from the back.
When someone gives you the short end of the stick, usually through trickery. Derived from how if you want a donut, but get a donut hole, you feel like you got a raw deal.
