undefinable, as it is only part of a joke
"Man, what did you do in here?... It smells like updog..."

"What's updog?"

"I don't know, Dawg, what's up wit you?"

An accounting joke used to pass the time. Interns and non-native US citizens most at risk to fall for this term.
I hate it when the up-dog appears in our workpapers.

Intern: What is up-dog?

Laughter follows.
