Dumb or unnecessary slang words put into sentences to make someone seem cooler in a conversation, but usually does the opposite.
Guy 1: That was a gnarly movie, dog! For real, the effects were polar!

Guy 2: It was alright.

Guy 1: And that girl was so fine! Straight dank movie, dog!

Guy 2: Quit the bad slang.
