Well, this is just stupid fun: The Profane Game. It's a pretty simple game where you enter profane language into a text box and see how many you can come up with in a minute. Stupid fun.
I got twenty five the first time I played and I did enter a couple that really should be considered a cuss, but it wasn't recognized by urban dictionary so it didn't count.
It's more difficult than it seems because of the time constraint.
