You hack the OS of a cell phone and when the user is typing, the autocorrect function is tunneled to the player's computer where he or she replaces what the user typed with something interesting and or witty.
The goal of the game is to maximize hilarity, irony, chaos. If your change makes it into their text, i.e. they send or post it, you get an extra prize.
This idea came to me last night during the debate when I typed in Jeb! and my iPhone changed to to Never!
