Sex bomb

Passing a local florist shop this morning, I noticed their display had changed and was now looking more like Valentine's Day. On pedestals in the window, in pride of place, rested two large-grapefruit-sized sacks, one red, one black, with the words "Sex Bomb" printed on each. Just what you want to give to that special someone in your life ... and a clever marketing ploy because it works on multiple levels. According to the Slovoed dictionary, bomb has a number of meanings: including failure; great success; or something unexpected and unpleasant. Hmmm.
