Noun: The phenomena that occurs in the absence of any discernible delineation between a human's belly and groin, so as to appear as if one was crotching a Christmas ham. The most significant existence of hampants witnessed to date is the groindomen of former New England Patriots/Notre Dame football coach Charlie Weis. This effect is accentuated when the subject tucks his/her shirt into their pants, most commonly a polo shirt of some type.
