The phrase was made known by the movie "Fast and the Furious" (2001) when Dominic (Vin Diesel) finds out Brian (Paul Walker) was incarcerated for "Boosting Cars".
Dom: Boost cars?
Brian: No, never.
Dom: Do time?
Brian: Couple of overnighters. No big deal.
Dom: What about those two years you did in juvie for boosting cars? Tucson, right? I had Jesse run a little background check on you, Mr. Brian Earl Spilner.
When in a race (normally from a roll) The operator of a "boosted" (turbocharged) car does a tricky maneuver involving applying brakes then adding in throttle to add more brake smoothly to eventually cause the engine to load up spooling the turbine creating boost/power while maintaining a constant rpm/speed so that when the driver lets off the brakes the car takes off like a bullet.
The car on the left brake boosted on that race.... didn't you hear the turbo spooling before they went?

I had a trucker's tan after driving for 10 straight hours on a sunny day.
