(n) frum um bo-The unpleasant odor from a woman's perineum region. Like 'from unda cheese' on a man and caused by the accumulative smells of the vagina and anus. A gumbo of smells..... Fromumbo
Naked girlfriend: dude, you have some from unda cheese smell going on.

Naked boyfriend: oh yea? Well I wasn't going to say anything but your fromumbo is off the chart today! Hey, shower time....

Naked girlfriend: You read my mind, let's go!
