The expression "chop-chop" is not specifically associated with English people. Instead, it has origins in various cultures, including Chinese and Malay. In English, "chop-chop" is an informal phrase that is used to urge someone to hurry up or do something quickly. For example, if you're waiting for someone to complete a task, you might say, "Come on, chop-chop!"
The term's usage in English likely comes from the influence of British colonial history and trade with Southeast Asia and China, where the phrase "chop-chop" has similar meanings of "hurry" or "quickly." It might have been adopted into English during interactions with people from these regions.
It's essential to remember that languages often borrow phrases and words from other cultures, and "chop-chop" is an example of how language evolves through cultural exchange and historical interactions. However, today, it is used casually in English-speaking contexts as an informal way to encourage someone to speed up or act promptly.
