The line comes from Worms Armageddon, the 1999 turn based artillery game by Team17, where worm teams announce actions with short themed voice banks. In the Brazilian Portuguese version, o primeiro de muitos is heard early in a battle after the first successful attack. Players who grew up with that dub began sharing the clip on soundboards and in edits, and its boastful meaning made it reusable far beyond Worms, as a shorthand for any first success that promises a repeat.
