A Canadian expression that means so many things, depending on the circumstances in which this phrase is uttered or heard. Probable meanings include but are not limited to:

• Shut up.
• You're an idiot.
• You piss me off.
• Liar!
• Don't bogart that joint, et cetera.

It should also be noted that Canadians don't really say this. Only those hosers Bob and Doug Mackenzie do.
