Those ugly-as-sin pants that have words written across the ass-cheeks. When watching a woman assvertising while she walks, you get this effect: "hillCREST" (step) "HILLcrest" depending on which ass-cheek is up. Severely not sexy.
Look, Tanya's decided to assvertise today!
"Should I buy these pants?" "Ew, no, those are assvertising pants."
