Giggity is the signature catchphrase of Glenn Quagmire, the libidinous neighbour in Seth MacFarlane's animated sitcom Family Guy, which first aired in 1999. Quagmire uses the word as a gleeful, self-satisfied exclamation whenever he sees something or someone he finds attractive, and the phrase quickly became one of the show's most quoted lines. Clips of the delivery spread through YouTube compilations, meme edits and soundboards, where its brevity made it perfect for reaction videos. It remains popular because a single giggity instantly conveys cheeky excitement without needing any context from the episode.
