Most of you already know, that especially Americans make a bad habit out of shortening almost anything to an acronym, only comprehensible for insiders. Two examples are YEO and YOYO, both of which, leave the user pretty much on his own.
YEO is for the classic James Bond fan and, therefore, very secretive, i.e. Your Eyes Only
YOYO is more for the dispassionate couch potato looking for not too exerting physical activity = You´re On Your Own
