Jadzia: Every time I hear someone talking about updog, I’m torn between not wanting to fall for it and wanting to help them complete their joke.

Sisko: Okay, but what is updog?

Quark: Updog is a long sausage in a bun, often served with ketchup, mustard, onions, and/or relish.

O’Brien: No, that’s a hot dog. An updog is when a new version or patch of an application is released.

Bashir: No, that's an update. You’re thinking of the fourth largest city in Sweden.

Garak: Surely, that’s Uppsala, where’s updog is the giant spider in Harry Potter.

Jadzia: That’s Aragog. Updog is a symbol conventionally used for an arbitrarily small number in analysis proofs.

O’Brien: You’re thinking of epsilon. Updog is an upward-moving air current.

Quark: No, that’s an updraft. An updog is the modern version of a henway.

Sisko: What’s a henway??

Jadzia: Oh, about five pounds.
