The line comes from 'My Lovin' (You're Never Gonna Get It)', the 1992 hit single by American R&B group En Vogue from their album Funky Divas. Built around a James Brown sample and the group's tight harmonies, the song became one of their signature records. Its hook proved especially quotable, moving from radio and music television into everyday slang for a confident refusal. Online, editors clipped the sung phrase on its own, and it survives as a reaction sound because the meaning is clear even without the full song.
