A person who demands the check be split between odd numbers of diners with no rhyme or reason thus making payment extremely difficult for me or Chris to figure out.
Occurs when a female places purse strap between her breasts causing clearly defined seperation of the titties, abnormal tightness of surrounding shirt material and sore necks for the double-taking males that are within sight. In addition, a titty splitty allows males to better approximate the size and shape of a woman's breasts.
The expression of splitty bitty bang bang goes back quite a while now. It was first found when one of my close friends decided to split their ballsack by reaching over for his homework.
