Instead of ringing the doorbell or knocking on the door upon arriving at another person's domicile, the ricer will instead rev the engine of their unnecessarily loud Honda, Toyota, or Mitsubishi.
Person 1:Did you hear that shit? Some ricer is just revving his motor in your neighbor's driveway
Person 2: Nah, that's just my hoodrat neighbor's boyfriend. He thinks his Civic is a fucking race car, so he rings the ricer doorbell whenever he picks her up.
Person 1: What a douchebag
