This is when a male dips his penis into melted cheese (preferably mozzarella) and shoves it into his partner's (or bitch's) anus and keeps it there for a few seconds. This allows the cheese to slightly harden, so when you pull it out and continue, she can feel... Everything. Don't stop even if she is in genuine pain, in fact, that's the goal. This is mainly used as a form of break up sex.
