Top definition. A girl with a huge ass. One's gauge is determined by taking both hands and extending both the thumbs and pinkies and putting one's thumbs together. The distance from one end of the pinky to the other is both one's gauge and the ideal width for a girl's ass. It is considered acceptable to go outside one's gauge within one hand length, but further than that is a complete "gauge buster" and should either not be done, or should be admonished by peers. I got cowboy drunk last night and ended up busting the shit out of my gauge with a gauge buster. I woke up praying she was gone in the morning, but she was in the kitchen shoveling cream cheese into her mouth with Ritz crackers.
RARE! 18 Yr. Old Gauge When She Was An Exotic Dancer Her douchbag boyfriend died of a heroin overdose in 2012 Saw her in a strip club in Arkansas before she got in the business. Good chance she was about 15. That was some crazy arm strength by Gauge. Gauge is hot, but I can't ever stand her douchebag boyfriend. This is a must see clip for Gauge fans. Her body was at it's peak and her little self introduction at the 3 minute mark is classic!
