The "I'm Not Your Fucking Brother motorcycle helmet sticker" is the boundary-setting vinyl decal for male riders who have had it with strangers claiming automatic brotherhood just because they're both on two wheels and have decided the policy needs to be posted somewhere visible. Brotherhood is earned, not assumed, and the helmet is now the official notification point for anyone thinking about skipping that part. The position is clear, the tone is appropriate, and the conversation is already over. Slap it on your noggin and let the sticker handle the introductions from here.
