A very bad insult originally made up by the online entertainer (not porn) Philip Michael Lester.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"
Phil: "I'll marshmallow your mum"
Dan: "im sure that's a disgusting sex act, right there."

To anyone here not because of Dan (aka Daniel Howell/ Danisnotonfire in the older days) and Phils (Amazingphil) recent Halloween video, then I apologise sincerely but you will have to look harder. For those of you who are then well done you are dedicated.
