    1/4 Mile - Pertaining to a 1/4 mile drag strip.
    60' - Sixty-foot time - The time it takes a vehicle to cover the first 60 feet of the racetrack. It is the most accurate measure of the launch from the starting line and in most cases determines how quick the rest of the run will be.
    Burnout - Spinning the tires in water to heat and clean them prior to a run for better traction.
    Holeshot - When a driver reacts quicker to the Christmas Tree to win a race against an opponent with a quicker E/T.
    Interval Timers - Part of a secondary timing system that records elapsed times, primarily for the racers’ benefit, at 60, 330, 660, and 1,000 feet.
    Tree - Also called a Christmas Tree, it is the electronic starting device between the lanes on the starting line. It displays a calibrated-light countdown for each driver.
    Tree (Sportsman Tree) - Used for bracket and handicap racing, consists of each yellow lighting 0.5 seconds after the one above it. The green comes on 0.5 seconds after the last yellow is lit. If the race is a handicap race each side of the tree will have its own timing.
    Tree (Pro or Full Tree) - Used in Competition, Super Stock, and Stock, for which a handicap starting system is used to equalize competition. The three amber bulbs on the Christmas Tree flash consecutively five-tenths of a second apart, followed five-tenths later by the green starting light. A perfect reaction time on a full Tree is .500.
    DR's - Drag Radials
    E/T - Elapsed Time or the time it takes a vehicle to travel from the starting line to the finish line.
    Heads-Up - Refers to a race in which 2 competitors
    Foul Start - Indicated by a red light on the Christmas Tree when a car has left the starting line before the green light, or starting signal.
    R/T - Reaction Time - The time it takes a driver to react to the green starting light on the Christmas Tree, measured in thousandths of a second. The reaction-time counter begins when the last amber light flashes on the Tree and stops when the vehicle clears the stage beam.
    Stage (Pre) - To position the front wheels about seven inches behind the starting line so the small yellow lights atop that driver’s side of the Christmas Tree are glowing. The next step is to stage and be ready to race.
    Stage - To position the front wheels right on the starting line so the small yellow lights below the pre-stage lights are glowing. Once both drivers are staged, the calibrated countdown (see Christmas Tree) may begin.
    Stage (Deep) - To roll a few inches farther into the beams after staging, which causes the pre-stage lights to go out. In that position, a driver is closer to the finish line but dangerously close to a foul start.
    Traps or Speed Traps - The final 66 feet to the finish line where speed is recorded.
    Weight Transfer - Pertains to vehicles with traction issues. The goal for RWD vehicles, is that they are set up to provide a desired weight transfer to the rear wheels. Upon acceleration, the front wheels lift and the weight shifts to the rear wheels, which makes them less likely to spin.

    You forgot ricer (Ricer: from the latin word Ricarius meaning to suck at everything you attempt)

    A person who makes unecessary modifications to their most often import car (hence the term "rice") to make it (mostly make it look) faster. The most common modifications are (but not limited to):

    - Huge exhaust that serves no purpose but to make the car louder
    - Large spoiler on the back that looks like something Boeing made for the 747
    99RCSB Broke because I wasted thousands and thousands of dollars on my truck.
