Forbidden words. Say one, give a point away.
Before setting off, agree on two to four forbidden words. Choose cruel ones: “car”, “no”, “mom”, “literally”, and the all-time killer, “are we there yet”.
Just… don't say them. That's the entire game and it's impossibly hard. Everyone polices everyone, and the catch must be immediate when a word slips out.
Say a forbidden word and every other player gets a point. Or, house choice, you collect a penalty point and lowest score wins at the destination.
Singing along with the radio doesn't count. Tricking someone into saying a word isn't just allowed; it's the entire point.
