(noun) The annoying effeminate giggle, titter or laugh occasionally produced my male homosexuals. This obnoxiousnoise is known to be especially painful to the ears of heterosexual males, but also is unpleasant to other homosexuals as it indicates someone trying to attract unnecessary attention to themselves. It is believed to have originated in humans as both a mating call for homosexuals, and a warning noise for heterosexuals.
Note that use of this term is not meant to be automatically disparaging against homosexuals, but rather against the terrible noise that merely happens to be made only by homosexuals, and then only by some individuals.
Guy 1: "Tee hee hee!"
Guy 2: "Dude, I don't care that you're gay, but knock off the gayggle, it's scaring away the ladies."
A group of college girls walking through or around campus. Usually found in groups of 3 or more. There is one girl that is the "leader" and controls the groups direction and speed. Decisions proposed by other girls in the group are either confirmed or denied by the "leader". The other girls in the group are ranked by their proximity to the leader. The group travels either in a straight line or V-shaped formation(much like geese). The group is loud and sometimes obnoxious to show their power status and/or to attract attention from males of the same species. They are neither walking to or from class, for their true mission is still unknown.
