A nikmulb is the act of fellating a womans clitoris while she is shitting on the toilet. Precisely the exact opposite of a blumpkin , which is why it is blumpkin backwards. Once you nikmulb you are highly praised among friends and can even join a special club for nikmulb'ers only.
"Yo dude, i totally just got fresh on some nikmulb after that party, she was such a slag."
