Since the debut of the Scooby-Doo franchise in 1969, several popular catchphrases have become synonymous with the characters therefrom. To wit:
- "Looks like we've got another mystery on our hands": Fred Jones' signal that another case is in the wings (akin to Sherlock Holmes' "The game is afoot!")
- "Jinkies!" Synonymous with Velma Dinkley, as in her signalling that an important clue has emerged. (In the Johnny Bravo crossover episode "Bravo Dooby-Doo," Johnny Bravo is overheard asking Velma "Jinkies ... Jinkies ... Is that a breakfast cereal or something?!")
- "Danger-Prone Daphne is stuck again": Also from Velma, referring to any awkward situation in which Daphne Blake is caught up in, only to stumble.
- "Ruh-roh--RAGGY!!!" Scooby-Doo's characteristic signal to Shaggy that the monster du jour is close at hand,
- "Zoinks!!" The characteristic catchphrase of Norville "Shaggy" Rogers, usually signalling that the monster is on the attack, and the chase is inevitable.
- "Would you do it for a Scooby Snak?" Usually asked by either Daphne or Velma as a way to get Scooby-Doo to help on the case.
- "Ta-ta-ta-ta-ta-TAA!! PUPPY POWER!!" Scrappy-Doo's entrance line, delivered in the style of a trumpet charge (and more often than not bombastically, usually to the annoyance and chagrin of the others).
- "Lemme at 'em! LEMME AT 'EM!!" Also from Scrappy-Doo, usually reinforced by his forepaws simulating boxing moves (howbeit comically). Sometimes requiring his Uncle Scooby to drag Scrappy by the tail and take him down a peg, as if sensing that the whole was rather dangerous for such a raw youngster.
- "And I'd have gotten away with it, too, if it weren't for those meddling kids!" The inevitable remark of the "real" culprit(s) behind the "monster," usually preceded with some sort of absurd tale to explain the circumstances.
