The phrase comes from Family Guy, the long-running animated sitcom created by Seth MacFarlane, where Glenn Quagmire uses it as his trademark expression of lustful excitement. First heard in the show's early seasons, it quickly became one of its most quoted lines, repeated by fans and reused in countless memes, reaction videos and soundboards. Its short, rhythmic repetition makes it easy to recognise even out of context, which is why it has remained a staple of online comedy long after its first broadcast, especially for jokes about attraction and flirtation.
