(Ri-ser fli bi) An action undertaken by a person fitting any or all of the genuinely accepted criteria of a "ricer" in which he or she accelerates a slow and underpowered motor vehicle, which is usually adorned with large spoilers, bright paint colors/graphics and neon lights, past another vehicle which is known or thought to be faster or more powerful with the intention of overtaking said vehicle at as high a speed differentiation as possible.

The act is typically used in lieu of a genuine speeding contest in which the "ricer" does not perceive any chance of succeeding and instead uses the action as a fabricated victory. The second vehicle is typically piloted by a driver who is unaware of any automotive competition beforehand, is likely driving in high-gear at low RPM and may or may not be adjusting the vehicle's stereo and/or scratching their genitals at the time.

The actual act of acceleration is usually very brief and surprisingly unimpressive and is usually accompanied by a very loud and irritating buzzing noise from the exhaust and/or the activation of the "ricer's" 4-way hazard indicators, which are used to communicate the bitch-slapping to the second vehicle.
Did he just do a ricer flyby??

In most cases, the "ricer" will later engage in spontaneous and excessive masturbation while vividly recalling his actions at which time the second driver will typically be having sexual intercourse with the "ricer's" girlfriend, wife, sister, daughter, mother or any combination of the above.

When a ricer and a other car race, the ricer loses, the winner slows down to legal speed, then the ricer flies by and thinks he won, to save some face in front of his friends.
"Dude, check out this ricer, he wants to race, check out his 4-banger Dodge Neon, my V-8 6.6 403 could whoop his ass."

*Ricer revs engine* *I rev back*

"We kicked his ass... oh her comes the ricer flyby... sure enough, probably thinks he won..."
