A large group of grad students at Penn State who drink away their worries every week (and usually multiple times per week) at a hole-in-the-wall bar. Generally only consists of science-minded grad students. (N.B. The "groovy" times do not always have to involve alcohol, and can, in fact, involve many different substances.)
Last night I went out with the Groovy Time Posse, and bitched about undergrads while taking tequila shots.
