Wow that Harley Davidson is as loud as a semi, too bad it doesn't have the horsepower to get itself up that hill!

A person who makes a lot of racket but does not go anywhere. Someone who thinks they are cool but are actually quite sad. Named after the Harley Davidson motorcycle because they make a bunch of racket and don't go anywhere, and often the people that ride Harley Davidson's think they are cool but are actually quite sad, and they have serious homosexuality issues.

When a man is injecting his penis into the girls ass, he pulls on her pigtails and then steps on her hands. This will make it look like he is riding a motorcycle and she will be purring like a harley.

All American motorcycle company. While the models of the 70's lacked quality, giving them a bad name, the company came under new management in 1981, and quality dramatically improved over the last two decades. Harley's are all about customization.

Instead of directly competing with their high speed Japanese rivals, HD exploits the retro style of the motorcycles to sell them. And if you take into consideration that even though Japanese bikes go approximately 50000000 times faster then a Harley, most roads have speed limits. This means that it doesn't matter a damn thing that your Honda or Yamaha can do 700000 mp/h, since you're only allowed to go 90, a speed no Harley has trouble reaching as well.

One thing that is a valid argument against Harley: the official Harley merchandise is ridiculously overpriced. A couple of hundred dollars for an official SD-card mp3 player? No memory card included? No thanks. However, if you're a millionaire, this shouldn't stop you from buying one of these bikes.

Well known models include the Fat Boy, Road King and V-Rod.
Alas, other Harley Davidson definitions still presume we live in the 70's. We don't. Welcome to the 21st century, where Harley's are good quality motorcycles again.
