Combination of "hygiene" and "gymnastics" describing the simultaneous use of feet, hands and elbows -- usually with a paper towel that you've used to dry off your hands -- to avoid touching any surface of a nasty public bathroom. One performs these feats of dexterity, for example, when trying to leave a gas station bathroom without touching any part of your skin to any surface.
