noun; clipping
Air conditioning My roommate is from Hong Kong and therefore has some different terms (mostly British) for everyday things. I think aircon has been around in British/international slang for years. Because the United States has chosen to shorten air conditioning to AC, they do not need to use the term aircon and I doubt it will spread.
Turn up the aircon - I'm hot.
Etymology : Shortning of the word air conditioning
