The BitchMcnigga is a type of black ass sandwich you get from McDonalds. They usually obtain this sandwich by burning the utter living fuck out of it to the point where its just a fatass piece of charcoal. Lil niggas most of the time think that shit tastes good when in reality they just eating garbage.
Friend: Yo they burnt my big mac bro.
Me: Thats called a BitchMcnigga, get it right u stupid ass.
