Cheesy double

When a man squats over a large vat of processed nacho cheese sauce, dipping only his testicles into the cheesy slurry, requiring that his partner will then lick off the cheese from his testicles. The cheesy double.

Stan: I heard that girl you got with was a total freak?

Frank: Yeah I had to call it an early night. She kept on insisting we try out the cheesy double and you know I'm lactose intolerant.
