Coined circa the early 2020s by online gaming personalities Wasteland Don and Scorpio Ku, prominent figures in the community surrounding the mobile survival game Last Z Survivor. The term emerged organically from the game's in-game chat and voice sessions, where the duo would frequently describe their post-night-out condition before logging on for early morning raids.
The word is likely a phonetic anglicisation of the German verkatert (hungover), itself derived from Kater (tomcat), the German colloquial term for a hangover — though Wasteland Don has suggested the spelling was entirely accidental, and neither creator was aware of the German connection at the time.

"Bro I was so katerted I thought I was still in the Wasteland."— attributed to Scorpio Ku, stream clip, widely circulated
From its origins in Last Z Survivor streams and Discord servers, katerted spread into broader gaming slang before crossing into general informal usage. It gained particular traction on short-form video platforms, where the phrase "woke up katerted" became a recognisable caption format.
It is now used widely in casual conversation and online communication as a vivid, slightly playful alternative to hungover.
