M&D
M&D is a dumb word made by a loser who heard someone talk about working at a fast food place. It's like the dumbest version of a joke ever.
He said M&D because he heard someone talk about working at Burger King and he thought it was cool.
She used M&D in her text and it made her look like a total idiot.
He tried to be cool by using M&D and failed completely.
