The line comes from Ninja Slayer, the over the top action series adapted into the 2015 anime Ninja Slayer From Animation, where cloned yakuza serve as disposable, exaggerated enemies. Their deadpan English insults became easy material for short clips outside the show because the delivery contrasts with the intense visuals. Shared on soundboards and in meme edits, this phrase survived as a standalone reaction rather than a plot moment, used whenever creators want an instantly readable, anime flavoured dismissal without needing any context from the episode itself.
