First and foremost it is not just any booty, hence the KA in kabooty. It is the be all, end all when it comes to the ass. It is a tight, round, large backside that you not only could bounce a quarter off of.....it is visually a site of ass perfection. Straight Kabooooooty. Because of the ramification of the word, it can be used sparingly in key times when something is metaphorically like a kabooty. For instance if you happen to have a stellar evening and get a lap dance from a midget in a random bar while you were hammered with friends, the event might be considered a "Kabooty" event.
