When a woman is taking a poop on the toilet & giving head to a man at the same time.
A man walks in on his wife taking a dump & says"Hey baby, how About a brown shmellkin?" The wife says "Sure" & gives her husband a blow job while continuing to defecate.
Brown for brown- that girl's boyfriend just went to jail and he usually supplies her with enough heroin (brown) to keep her well, Guess she will do what she always does give up the ass for brown. Brown for brown
