Just come across the idea of “man caves”. Not sure if it’s really old news, but a great idea either way. It seems to be an American celebrity trend from a couple of years ago, with the likes of Brad Pitt having these woman-free zones to keep all their cool stuff and get away from it all.
Urban Dictionary definition:
“A room, space, corner or area of a dwelling that is specifically reserved for a male person to be in a solitary condition, away from the rest of the household in order to work, play, involve himself in certain hobbies, activities without interuption. This area is usually decorated by the male that uses it without interferance from any female influence.”
Basically what Brits would call a den.
Here are some cool man caves.
