Done by a ricer after losing a race. It's the racing equivalent of a sucker punch. It goes like this: the race is over and the winning car is slowing down but the losing car just keeps going and flies by at (what seems to them, at least, to be) a great rate of speed.
I saw a Z hand a ricer his ass, who promptly did a flyby.

Done by a ricer/meat head after losing a race. It's the racing equivalent of a sucker punch. It goes like this: the race is over and the winning car is slowing down but the losing car just keeps going and flies by at (what seems to them, at least, to be) a great rate of speed. The losing car will most likely resemble the sound of an amtrak train (meat head) or a weed wacker (ricer).

A quick and discreet "pass-through" of a nearby area to check on a repairman's progress, observe if certain persons are present, etc. Practiced by a considerate person who doesn't wish to hover, or when the actor prefers not to reveal his presence or disturb anyone until the appropriate time.
Customer: I wonder if the mechanic is done with my oil-change yet... think I'll do a discreet flyby of the garage and see what he's doing at the moment.
