where did the term man cave come from
Man cave A man cave[1] or manspace,[2] and less commonly a manland or mantuary is a male retreat[3] or sanctuary[4] in a home, such as a specially equipped garage,[5] spare bedroom,[4] media room,[6] den,[7] or basement.[7][8] The term "man cave" is a metaphor describing a room inside the house such as the basement or garage or attic or office, or outside the house such as a wood shed or tool room where "guys can do as they please", without fear of upsetting any female sensibility about house decor or design.[9] Paula Aymer of Tufts University calls it the "last bastion of masculinity".[9] The phrase is thought to come from the 1993 publication, Men Are from Mars, Women Are from Venus.[10]
