Definition of chopper

The origin of the word "chopper" refers to a type of aircraft or helicopter, particularly in the context of aviation and military operations. The term "chopper" emerged in the mid-20th century, around the 1950s to 1960s. The word is believed to have originated from the sound of a helicopter's rotors chopping through the air, creating a distinctive chopping or "whooshing" noise when in motion. Pilots and aviation enthusiasts began using the term "chopper" to affectionately refer to these vehicles, which were also known as helicopters or whirlybirds. Over time, the term "chopper" evolved to encompass other meanings, such as a chopper bike (a motorcycle with a chopped or modified frame) or a chopper knife (a specialized type of knife used for chopping or cutting). However, its primary association remains with helicopters and aviation.
