A response to a ridiculous inquiry or request, loudly and in the manner of a classic stool pigeon, intended to thwart the inquirer and used to indicate that you're not going ot buy into their fakeness/foolishness by responding in kind. Oft followed or preceded by a "Myeah" declaration.
From Dave Chappelle, who noted that particularly fake people often unwantedly elicit equally fake responses from others.
Beezy: "Oh my god did you hear about the catfight Lindsay Lohan got in last night?!"
You: "No, see!"
