When I played this and saw the types of responses in it, I thought it would be right up your (the site's) alley.
Here's the link to it if anyone is interested:
http://pyx-2.socialgamer.net/game.jsp#This is a webapp based on a card game called Cards Against Humanity. Object of the game is that on each round, one player asks a question from a Black Card, and everyone else answers with their funniest White Card. The one asking the question "the Card Czar" picks the best one and the person that played the card that was picked gets the point. Some of the responses can be NSFW but I'm sure that wouldn't bother most of you.
You don't have to download a thing. I believe it's browser based. You can have private games as well by setting a password for the room. There are some videos on youtube if you want to see how it plays. If anyone is interested, give it a try and see if you like it.
