Related to abbé: Abbé Sieyès
slang To rappel down from a mountain-climbing route. "Ab" is a shortening of "abseil," a largely British term meaning "rappel." Primarily heard in UK. The climb itself is very challenging and fun, but there's nothing to do once you reach the top, so I usually just ab off straight away when I finish the climb.
