The phrase comes from Dragon Ball Z during the later sagas, when Super Saiyan is no longer limited to Goku and Vegeta and younger fighters like Goten and Trunks can transform with ease. Vegeta, who treated the form as a matter of Saiyan pride, became the natural voice for complaining about it. Clips of the line later circulated on soundboards and in anime edits, where fans reuse it whenever sequels, games or fan works hand out transformations that once felt unique and hard earned.
