A sweet-ass suite in Craige dormitory at the University of North Carolina at Chapel Hill. Not much is known about ManCave other than that they drink large amounts of beer, have a strict entrance policy and dress code, and are rumored to have beaten Super Mario World on the Super Nintendo.

I would guess that this would be a puerile diversion that is a temporary regression to the psychosexual stage of development known as latency (the ages between 5 or 6 to the time of pimples and interest in girls) with the upper middle class and above. You would need a house with space for a possible knockabout mannish place where lace is not allowed.
This would offer a respite from events that are stressful and jettison to a time when the demands of adulthood morph to the days you hung signs on clubhouses, " No Grils Aloud."

It's a way of life
