A fly ass nigga with whom you hang out with. Typically the funniest person you know. Typically a BDM is a large and tall overweight male who mostly wears a white shirt, glasses, cargo pants, a jacket, and only the most fly shoes. BDM is the one who brings you happiness and he's also the one you can count on the most.
Male 1: "Hey, what are you up to BDM?"

BDM: "Not much, just doin' typical stuff."

Male 1: "I've been thinking, why does 'BDM' even stand for?"

BDM: "Big Daddy Marshmallow"
