wait. cancel post. gung-ho cannot be English. where did that phrase come from? China?
ok, yes. gōnghé, which is…an abbreviation for “industrial cooperative”? Like it was just a term for a worker-run organization? A specific U.S. marine stationed in China interpreted it as a motivational slogan about teamwork, and as a commander he got his whole battalion using it, and other U.S. marines found those guys so exhausting that it migrated into English slang with the meaning “overly enthusiastic”.
