Oki doki loki is one of Pinkie Pie's best-known catchphrases from My Little Pony: Friendship is Magic, where the pink earth pony is famous for her boundless enthusiasm, party planning and fourth-wall-breaking humour. The phrase spread through fan edits, reaction videos and soundboards, where its rhyming, musical bounce made it easy to reuse as a quick yes. It remains popular because it instantly signals Pinkie Pie's personality, even to viewers who only know her from short clips.
