Debuff is a long established game term for a temporary effect that lowers a target's stats, the opposite of a buff. Clips labelled debuffe circulate on soundboards as a quick shorthand for that moment, shared between players who recognise the cue from role playing and strategy games. Instead of explaining a nerf, a slow or a stat drop in text, creators drop the sound and viewers get the meaning straight away. It stays popular for edits, live streams and short form videos where a clear audio signal for losing power saves time and adds comic timing.
