Don't Be That Guy is a casual party-style card game which highlights the annoying natures of other people. Each card presents a situation that is found by most people to be irritating (Examples: Driving slowly in the left lane, Teaching someone's child to swear, etc).
Game play is as follows: (Normal Rules)
One player reads the card and shows it to the other players.
Each player votes to see which player is most likely to be guilty of this bad habit. The person with the most votes is "That Guy" and receives the card. The first person who hits 7 cards loses, as the game is called "DON'T be that guy".
Alternate Rules:
For groups where people are not as familiar with each other, before the first card is read, each player chooses a famous person (real or fictional, male or female, etc) and plays as that person for the rest of the game.
