The act of causing rapid evacuation of a room or other confined space by floating a particularly nasty air biscuit. Most commonly, a grierson requires the assistance of a tarka for maximal effect. The word is derives from the name of a rotund large-eared red-headed gentleman scholar of an unathletic nature (not to be confused with a waby), who claimed to be able to clear the audience of a 300-seat lecture theatre in 10 seconds.
