An acronym for Rich Urban Biker. A title given to middle aged, upper class, white males that make more money than they know what to do with so they decided to pretend to be bad ass and get a Harley. Unlike real Harley men they get all the trimmings on their bike which usually includes Heated handle bars, luggage racks, stereos, raised back support, cruise control and completely useless items like suicide shifts. Basically they just end up buying a 2 wheeled sedan, but they have no idea how to maintain it.

You’ll never see them exceed the speed limit; actually, you’re lucky to see them ever DO the speed limit.

Any damage that may occur to their Harley will instantly run them at least $2000, merely because of all the bloated accessories they’ve placed on the bike, because of this, they will only take their bikes out on the sunniest of weekend rides and only for short distances. Even if they’re going to some sort of Harley riders get together, they would rather tow their bike in the back of their truck, stay at a nearby Hilton and will only ride their bike a couple of miles from the Hilton to the “meet” the day of the convention.

RUB’s are the only motorcyclist who DO NOT give a waive or a nod to other riders on the road when passing, apparently they are to smug to do so or afraid of crashing by doing something complicated like nodding.
only a RUB would have heated handlebars on a bike

Random Ugly Bitch. A game played by guys in which the whole group looks around a room, then stares at the RUB until they either blush or go away. IF she stays they walk over and say to her shes ugly;if she runs they yell it out. Either way its fun.
