marshmallow your mum

A very bad insult originally made up by the online entertainer (not porn) Philip Michael Lester. Is often said with little or no context. Is said to never be looked up on Urban Dictionary.
Dan: "I'll hide the marshmallows down your throat
Phil: "I'll marshmallow your mum"
Dan: "im sure that's a disgusting sex act, right there."
Phil: "don't look that up on Urban Dictionary"

Cheese-Marshmallow Theory

The idea that any food can taste better by adding either cheese OR marshmallow.

Yet to be disproved, however the Cheese-Marshmallow Theory is unlikely to become a law due to the fact that it can never be proven.
Julian: I got it! Cereal...
John: Marshmallows...Lucky Charms man. Trust me, I was a non-believer at first too but you'll come around. The Cheese-Marshmallow Theory can not be disproved!
