The place in your work/school/house that you feel most comfortable defecating(taking a poo).
In colleges or work this is the bathroom that is usually the cleanest, and least visited bathroom. No matter what time of the day you can take a dump comfortably without worrying about your friend coming in and recognizing your shoes. You usually get so comfortable that you find yourself
surfing the web or even dozing off in your HQ loo.
In homes
the only thing that is different is that it is where you keep all your
miscellaneous items. So that you can make the poo experience more enjoyable. For examples magazines, puzzles, or even a tv.
You get a text from your friend
Friend: Where are you? There are free donuts in
conference room!
You: Aw man, get me one I'm in my HQ loo!
Friend: looks like your sh*t
out of luck...no pun
