The Brief: Clapped is a slang term meaning destroyed or taken down.

DEEP DIVE
Deriving from British slang for “being shot and killed”, clapped has been adopted by Gen Zers to mean being destroyed or obliterated, most often in video games or hyperbolically, in sports.
Getting clapped goes beyond taking an L.
