It is immature it is dumb but I can tell you this there are plenty of college kids that would live for games like this.
Drinking is immensely popular in many colleges and drinking games are one of the most common forms of college drinking (see beer pong and others).
The real problem is that their really isn't a shop that wants to carry a game like this I would think if there were a novelty shop it might be the best bet (maybe spencer's gifts style) it is just there are so few of these kind of shops that the market reach for this kind of game is limited.
My point was that this is what the rejections are telling you too.
