Deaf Skype
The rules of the game are simple, while on a video call, neither participant are allowed to talk, so they must type what they want to say. Useful mostly in college, when one or both of the skyp-ee's roommates are doing homework or sleeping, as not to disturb them.
Hey, I don't want to keep my roommates up so let's deaf skype, that way only the light from my computer will keep them up.
