It is usually used as an exclamation.
Vootie originated in 1955 in a Mad Magazine parody where Dave Garroway's chimp (J. Fred Muggs - who also painted a cover for Mad) takes over the show. Instead of Dave's signoff, "Peace", the monkey said "Vootie". It was later used in 1996 as an exclamation in Star Control 3 by a race called the Xchagger.
We be answering YES! Hearty! We be thinking you'd be never asking! Vootie!
