A pink frosted, rainbow sprinkled donut. Also used for cleaning windows, according to Smosh and Wikipedia.
Ian: If you used Wikipedia more often, maybe you would know that before donuts were used for eating, they were used for cleaning windows.

He then washes a car window with his pink frosted sprinkled donut, although it doesn't work well.

This is when you take a long shit and roll it into a donut shape and cum on the top of it. You the freeze this donut shaped, cum covered shit to make the cum into a glaze consistency. After this is ready, remove the shit from the freezer then finger your girlfriend, wife, or depending on the state, your sister, while she is on her period, then flick your fingers over the donut to give the donut the appearance of sprinkles. When this is done, serve it at the next family dinner to the in-laws.
Wow this frosted donut tastes really unique. What's in it?
