This term is used to describe a show car that travels around in a trailer. There are two general types of trailer queens.
1) A car that, for some reason, can't or shouldn't be driven but is still show worthy. For example, some cars are too old to be safe to drive cross-country so they must be trailered.
2) The most common trailer queen can be driven. The owner is ussually so tied up in the status and appearance of his car that he has forgotten the joy of driving it and now hauls it around in a trailer to avoid dirt. These are often painfully shiny with very expensive, detailed painjobs and excess chrome. The owner will wash and polish every part of the car (even the brake pads) before the car goes in the trailer and then again after he parks it at the show. Extreme trailer queens are often hauled around in trailers that are show-worthy themselves.
We had fun driving our cars to the show but that trailer queen is so tied up in making his car extra shiny that he's gonna be polishing the thing until tommarow.
A person who takes his classic car to car shows on a trailer, then jumps out and starts polishing off all the invisible dirt that might have attached itself. Trailer queens don't drive their cars. They just drag them around on a trailer to be admired.
Look at that Corvette! I'll bet the trailer queen hasn't started it up in 14 years.
Derogatory motorcyclist slang for a show bike which is rarely or never ridden, but is hauled to shows on a trailer for display only.
It looks great, but that trailer queen is 5 years old and has less than 50 miles on the odometer.
