Obscure reference to the Simpsons:
Monty Burns has just made a speech, and was getting booed out. When he asks his kiss-ass assistant if they're booing him, he replies "No, sir...they're saying boo-urns." He then asks the crowd, and they continue to boo him, save for
Hans Moleman, who says "Well, I was saying boo-urns."
An exclamation, used in disappointment or excitement
