According to Wiki a man cave is the following; A man cave or manspace, is a male sanctuary, such as a specially equipped garage, spare bedroom, media room, den, or basement. It is a metaphor describing a room inside the house where “guys can do as they please” without fear of upsetting any female sensibility about house decor or design.Paula Aymer of Tufts University calls it the “last bastion of masculinity”.
While a wife may have substantial authority over a whole house in terms of design and decoration, she generally has no say about what gets “mounted on the walls” of a man’s personal space. Since it may be accepted that a woman has input on the decoration of the rest of the house, a man cave or man space is in some sense a reaction to feminine domestic power.
Some people love the term “man cave,” others hate it, but the idea of a room dedicated to “manly things”—cigar smoking, scotch drinking, football watching—is something that’s been around for a while now. Most in 2014 are tasteless, smell like chips and salsa, and feature a bunch of crappy Lay-Z-Boy sofa, but these ones from way back in the 60’s and 70’s have a certain kind of vintage cool.
