cheaply constructed polyester/lycra pants easily distinguished by lack of back pockets. asspants are typically tight around the posterior and thigh areas, with a tacky 'flare' from the knee down. despite being available in an array of colors, the most commonly adorned pairs are black, followed by white. asspants are typically worn by clueless women with low self-esteem who attend clubs and bars in search of horny men. woo-girls are typically the greatest offenders.
"the club was filled with chads and slutty trollop woo-girls wearing their abominable ass pants."
