(noun) Any gathering of two or more women who begin to talk loudly and nonsensically over one another about useless things, much the same as a group of chickens clucks wildly and noisily, without exchanging any actual knowledge or really accomplishing anything at all.
Mark: "Hey, you hearin' this noise in the next room? What the fuck are all those broads yelling about?"
Steve: "Engagement rings or some shit. Total fuckin' cluckfest in there."
