1. Two fat people that met in a donut shop, because theyre fatties, which results in sex.
2. Both people are so fat that the guy cant tell / does not care if what hes sticking it to is the hole of the woman or the hole in the donut
3. It looks so good and yummy, but it ends with being completely exhausted, feeling fat, and regretting it afterwards
( also: donut shopping, a donut shop, to donut shop, and so forth)
