The voice belongs to Homero, the Spanish-language name for Homer Simpson from the long-running animated series The Simpsons, which began in 1989. In Latin America and Spain the dubbed version is the one most viewers grew up with, so this shout is instantly recognisable there. The short clip spread through soundboards, messaging apps and short video edits, where the stretched pronunciation in searches like homero neeeerd became part of the joke. It remains popular because one word, delivered in that familiar voice, works as a complete teasing reaction without any setup.
