Very popular cartoon about a dog named Scooby-doo who runs around with his friends Shaggy, Velma, Fred, Daphne, and sometimes his young nephew Scrappy-doo and cousin Scooby-dum. Scooby and his gang have been solving mysteries all over the country since the early seventies.
Scooby-doo: Ruh-roh
Shaggy: Zoinks!
Velma: Jinkies! We've solved another mystery!
Daphne: haha yaaay!
Fred: Good work, gang!
Perpetrator: I would have gotten away with it too, if it wasn't for you meddling kids and you're stupid dog too!
When the writers of a film run out of funny and interesting dialogue and resort to using a pop-culture reference as a cheap gag.
"Hey Erik?"
"Yeah Chris?"
"What should we have the wizard man tell the kids to continue the plot in a funny way?"
"idk, make him say "Scooby-Doo this crap", that'd be hilarious."
