An acknowledgement that shows you know someone is telling a lie. Also sometimes used inadvertantly by the liar in the process of lying. First used in this manner by a York High School heavyweight notorious for his fabulously fabricated stories about what he did that weekend.

"Really?"
"Yeah dude, it was awesome!"
"Yeah dude."
"No really, it totally happened!"
"Yeah dude, I totally believe you!"
