In these hectic times, nearly everything can be said in an abbreviated way. For instance, saying "vaca" instead of "vacation" allows you to save time when you want to tell your coworkers, "I'm a pretentious ass."
The ultimate form of shortening is the acronym. With acronyms coming out the YY*, it's hard to keep them straight. I was reminded of that when I read the headline, "FBI gives cops critical info: how to spot an IED"
IED: Improvised Explosive Device
IUD: not an IED.
* = Ying Yang
