A person who believes that pure American muscle cars are the best cars on Earth despite the fact they are only good at straight lines. Defining traits include a cocky attitude, quotes such as "should've bought American" or "be a real man and drive a Chevy/Ford/Dodge", and pure insecurity. Please do not get confused with people owning muscle cars who actually have respect towards others.

People in background: bro we're just trying to have fun.
