One who does exceedingly stupid or irrational things, usually but not necessarily while under the influence of drugs or alcohol. The word is believed to have originated as a spin-off of the 1976 ABC sitcom ‘The Gong Show’ where participants would perform until the judges deemed their performance too awful to continue. Note: gong show is commonly abbreviated to 'gong'. The act of calling somone a gong show is often accompanied by two of his buddies bashing an immaginary gong.
Wow, he's got vodka taped to his balls, what a gong show!
Tribe, your a fuckin gong show!
He just slid head 1st into a giant mud puddle 10 minutes before his philosophy exam, what a gong.
