M & M party
An M & M party is when you put M & M candies up a girl’s butt or in her snatch and make her eat them, or you do it to a guy and let him eat them while you blow him.
"He put M & M’s up my butt and made me eat them while he sucked my cock like a hungry kid."
"My girlfriend had M & M’s in her snatch and I had to eat them like it was a test."
"He put M & M’s in my butt and I had to eat them, it was like a candy-coated punishment."
