Reminds me of the Omegle zombie survival game:

1. You have six shotgun shells.
2. Connect to a random person.
3. If they ask “ASL”, they’re a Zombie. If you have a shotgun shell left, you shoot them and use up one shell. If not, they bite you and you die.
4. Ask “What is OP?”. If they give the correct answer, they’re a fellow survivor, and both of you refill your shotgun shells.
