The word of the day is Man Cave.
Even Major League Baseball created a “Fan Cave.”
My wife remarked, “To me, so many of these man caves seem more like man HOLES.”
Well, try marketing vintage neon beer signs and other tough-guy memorabilia to someone for his hole. Regardless of how dark and dank his basement space might appear to others, CAVE is the required term.
Bears. Batman. Baseball fans on a reality show. They all agree. Party in the cave!
