Thanks tsuwm and now that I was there I took the tiny trouble to import it:

Word
"Slang; Used to express approval or an affirmative response to something. Sometimes used with up."

Quote:

This explanation makes sense, but the first sentence I read in your link made me laugh "verbum nullum fecit"

Luke, if I did not love my country, (monarchy or no monarchy) I would not live there.
