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.
About this sound
Vegeta's frustrated Super Saiyan bargain sale line from Dragon Ball Z, used as a reaction when something rare suddenly becomes common or cheap.
This is a short voice clip of Vegeta reacting with disbelief as Super Saiyan transformations stop feeling legendary and start happening everywhere. His delivery is annoyed, proud and a little insulted, as if a rare power he worked for is now being handed out for free. The line lands in a few seconds, with the frustration building on bargain sale as the punchline. For viewers who know Dragon Ball Z, the humour comes from that contrast between the old myth of the Super Saiyan and how routine it later becomes.
