The decorative bow or bows found on bras and underwear. This is a sniglet invented by myself and several cohorts, and makes for a great conversation piece (especially if you are trying to seduce someone) :) The name arose one day in the food court of a mall after a trip to Victoria's Secret.
Technically, it should sound like Oh!' Ja' ma' Bow(just like it is spelled). The "oh" part comes from the surprise of a seperate party/SO when they discover a bow on the bra. I have no clue where the "jama" part comes from, I think we just needed some filler in the middle so it didn't end up Oboe, and of course, "bow" is....well, the bow.
