Paula Aymar (a woman) as 'the last bastion of masculinity'. Earlier described in the 1990s, when so many trends were 'discovered' by simply putting a name to them, as the man's 'cave of solitude' — again by a woman, Joanne Lovering, a journalist then with the Toronto Star — it would seem the mancave is a Darwinian space the male of the human species requires for peace of mind.
The corollary being that women don't need its equivalent: a womancave or she-shed.
Truth be told, the notion of women being far less anti-social, in need of 'me-time', is peddled as much by women as by men. For concocting the gender-specificity of every superman's Fortress of Solitude, and tucking him there, automatically gives every superwoman her own feet-up leisure space minus any other company, man, woman or child.
Whatever one engages in within the four walls of moments of happy solitaryhood no longer being gender-driven outside the world of advertising, the mancave could well be the best concocted space providing not just men or women separately, but humans in general, get their quality me-time. As culture is largely dictated by media-ted notions, the beer of the mancave could, though, be replaced with white wine.
