1. When a person is has chirped the tires; it simply means that they put enough foot down on the gas pedal to make the tires chirp. It's not like they are smoking their tires; they just hit the gas enough to get a "chirp" sound from the rubber of the tire as the tire turns fast against the road.
1. I could not believe it! I was out with Grandma and she was driving and Grandpa and I were riding; and then GRANDMA chirped the tires when she took off! She was sick of the guy next to us cutting in and out of traffic so she chirped off and beat him to the next intersection before he could cut in front of her again. I was cracken up!
