look up any word, like sex:
 
1.
When two seemingly heterosexual, but secretly homosexual has a breakout on a public dance floor, removes their clothing and acts in an extremely homo-erotic way whilst screaming, "MARTY SANDWICH"

Please note that sometimes the term "WITHOUT THE WRAPPINGS" is yelled as a metaphor to describe their shirtless state, "With the fillings" is when they put a female companion in between their shirtless beings as a form of homo-erotic torture.
Stan: "Damn, the music is good in here"
John: "It is so mate, GUESS WHAT TIME IT IS?"
Stan: "Mate, ;) MAAARTY SANDWICH
(Electro-Funk music in the background, John and Stan proceed to remove clothing and move uncomfortably close to one another)
John: MARTY SANDWICH WITHOUT THE WRAPPINGS!!
