A modified, customized motorcycle, typically a Harley Davidson, although "back in the day" Indian, Triumph and BSA motorcycles were "chopped" and these days Japanese motorcycles are being transformed into choppers.

The term "chopper" comes from the origins of motorcycle customization. Unnecessary parts were (sometimes literally) "chopped" off to reduce the weight of the motorcycle and increase its performance for racing. Rear fenders were "bobbed" (where the term "bobber" comes from), front fenders, crash bars, saddlebags, windshields, head and tail lights, kickstands, mufflers, etc. were all discarded to improve the machine's power-to-weight ratio. Forks were extended to improve ground clearance and later raked to compensate for better stability.

Contrary to popular belief, a chopper is not simply a motorcycle built with long forks, a stretched frame, chrome and billet crap and a gazillion-color $10K paintjob. True choppers are generally built from another motorcycle or motorcycles, by the owner of the motorcycle and modifications are done to the builder/owner's desires and usually done on a budget.

The big-bucks "chopper" shops do not build choppers. OCC does not build true choppers. They build custom motorcycles. A custom can emulate the classic chopper styles (bobber, East Bay lowrider, digger, fat bob, etc.) but it is not a true chopper. Same as a fibreglass-bodied 350/350-powered 5-window coupe that looks like a hot rod, it is not a true hot rod.

chopper (commonly pronounced choppa) is the nickname for the Thompson sub-machine gun a.k.a. the Tommy Gun. The word is derived from the sound it makes when being fired in full automatic mode which makes a chopping sound. The word is now used in pop-culture particularly in rap music to describe any kind of fully automatic sub machine gun.

A middle class male who fits most, if not all of the following criteria. Not to be confused with a rah.

He has floppy shoulder length, usually blond hair.

He visited South East Asia for his gap year, but he doesnt call it a gap year he calls it "travelling". What he actually means is he got shitfaced with other choppers for 3 months, all the time posing with the the poor local children for a host of Facebook profile pictures.

He is paid through university by his family and finds it strange that not everyone gets the same deal.

His year round attire is a pastel coloured polo shirt, three quarter length beige shorts and flip flops.

He drives a Mini.

After finishing his degree in Business Studies or Management he will get a job working for his dad's company.

He has a tattoo on his arm (often from his "travels") that he considers to be meaningful. It shows his creative side. It says "TWAT" in Vietnamese.
Look at that guy at the bar, he's a complete chopper.

Davey: Mate, you are a complete and utter chopper.
