A word used usually on AIM or on the phone. It is a POS (parent over shoulder)kind of thing. When someone for example a parent or sybling is around when you are on AIM you could randomly type achoo to hint to tht person on aim not to say something. Say you were on the phone though and your friend wants you to say something but you cant because someone is around..you simply ACHOO. The friend wil take the usualy take the hint and change the subject.
You cant sneeze though..you must say achoo in away tht cant be confused with a sneeze.
