f8r is short for "fair" usually used by a sore loser while playing truth or dare. This person usually ruins the fun and victimizes itself saying that everything it's too much for him while the others are perfectly capable of what this mere mortal isn't.
Person A: "I dare you to call your mom and tell her you can't find a girlfriend in a very panicked voice."
Person B: "No! That's not f8r! You had the easy ones!"
Person A: "Boi"
Person C: "And that's why you can't find a girlfriend."
