as marketed by Spike TV

Right. It's just a place to stick your cheap plastic collectibles, as romanticized by the man-equivalent of the home shopping channel. You see it on home improvement shows all the time, as well, typically themed to some hobby or consumer franchise. And back in the '00s, sitcoms got in on the racket, with every Family Dad having an episode or three that involved renovating a basement or spare bedroom.

Side note, remember when houses had a room called the “den”?

I've also heard it called the TV Room, the playroom, and the family room. Most houses still have it, typically adjoining the kitchen/dining room. My house has a second-story flat that's kitchen, dining room, and den laid out in a single open rectangle. We have the TV on the back wall and you can see it from the other side of the house. But all the entertainment - the record player, the video games, the little rolling dry bar I have in the corner - is on the "den" side of the house.
