Grups is a term for adults who, in subconscious desperation, dress and act way younger than they are. Pushingfortys who go to clubs and sport grunge hair, goatees, jeans, and video iPods loaded with emo, Arctic Monkeys, and Everwood. What it is is “grownups” with the “own” removed. Because, frankly, there is no own anymore. Grups is the subject of a story in the current New York magazine, a publication that has been a journalistic grup for decades without realizing it.
