Any kind of long metal bar/club, usually cylindrical, used to hit somebody, usually with the intent of kocking the person out. Usually used by hitting the person over the head. Not necessarily something designed specifically for hitting people, but rather, any metal bar may be dubbed a "pomp".
"That cop has a pomp hanging from his belt"
"I was looking around in the pile of debris to try to find a pomp, as the group of gang embers were moving on me fairly quickly, and I needed to defend myself."
