when a worker at a donut shop, usually Krispy Kreme or Dunkin Donuts, cums on the inside of a jelly donut instead of filling it. Sometimes if the employee is either really daring or high, the cum will replace the icing on top of the donut.
Dude, I got fired yesterday for serving one of my cum donuts to a customer.
