The phrase comes from the fighting game community, where teching has been a core defensive mechanic since Super Smash Bros. Melee in 2001. Players began shouting it at tournaments and on streams whenever someone survived a seemingly guaranteed knockout, and clips spread across YouTube, Twitch, and Discord servers. It became shorthand for skill under pressure, similar to other callouts players reuse as reaction sounds. Its short, confident delivery keeps it popular for edits long after the original tournament moments faded.
