"Good Point, Sport." -- acronym GPS-- is an often nonchalant and naive term given in response to someone who has outlined a well-though out scenario or eulogy to an argument between two peoples. This term can also be used instead of the typical, "Touché". Girls by the name of Janet will frequently use "GPS" as a form of undermining a person who has proven a point.
Typical chick named Janet: "Chicks should wear yoga pants all the time!"
"Nope. Chicks at least shouldn't wear yoga pants when they're not doing yoga and/or when it's cold. It's not fair. Makes us dudes look like perverts."
