The thing Telly from the film Kids (1995) said to the shop keeper as a distraction, so that Casper can steal a drink.
Telly: (to the shopkeeper) Excuse me would you happen to have diss digg?
Shopkeeper: What is diss digg?
Telly: Diss digg I'm just curious if you have it.
Shopkeeper: I don't understand what you're saying, 'thirsty'?
Casper: (to the shopkeeper while walking out of the shop) He said 'this dick', motherfucker! Don't you understand English?
