a bastardization of "den" or "study" that has brought shame to the english language. man cave is one of those words that makes the listener shudder.
origin of man cave: coined by a slob at the end of the first decade of the 21st century, the repulsive word "man cave" was picked up by a growing population of people with bad taste to describe a deplorable emerging phenomenon of banality. whereas in the past, men who were lucky enough to have an extra room in their houses would generally use them for research, writing, or other constructive activities, a certain new group of men with an abundance of resources and nothing upstairs, began using their extra rooms for sloth and hedonism. words like "study" could no longer be used in a coherent way, while more accurate words likes "porn room" had too many negative connotations. thus, man cave was created to describe this unfortunate consequence of a society afflicated by the disease of affluence.
essential characteristics: man cave is a place where an over-sized slob sits in an over-sized arm chair in front of an over-sized tv and looks at ugly women with over-sized breasts, in a part of the house away from his over-sized wife.
wife: why dont you spend any time with me anymore? youre always in that damn room!
husband waddles to towards the basesment
wife: good! go to your man cave. i dont want to see youre ugly face anyway. i know what you do down there! you filthy bastard!
