Nextbots are the player-chasing characters popularized by Garry's Mod mods and later by Roblox's Nico's Nextbots, and Cootie is one of the community's favorite chasers. Its short looping audio spread through chase compilations, fail edits and soundboard uploads, becoming shorthand for an incoming ambush. Like the vine boom, it works as an instant meme cue that viewers recognize in under a second. Years after the nextbot craze peaked, creators still drop the Cootie sound whenever a video needs a sudden, silly burst of panic.
