Why does all of the fun shit happen on the opposite side of the country? Back when I lived on the West Coast, all I ever heard about were the awesome cons on the East Coast. Now that I live on the East Coast, all the awesome cons happen on the West. <

Nope, not setting a foot on US soil voluntarily until that government has abolished its biometric data collecting.

... but the term "hemisphere" is actually used only to define souther/northen hemispheres.

I don't hope beeing addicted -as you call it- taking everything to the letter.
I hope I do not appear as an insufferable know-it-all to you.
But I do appreciate being specific and accurate. Unfortunately nowadays it doesn't seem to be a desirable virtue to express oneself precisely.

I'm sure even in Portuguese the word Hemisfério means more than just northern and southern hemisphere of the earth. Unregarded of how propably most people use it in the public with a certain meaning (which doesn't justify poor or wrong use). I'm sure there is more if you look it up in an proper encyclopaedia (not necessarily WiKipedia!).

Just to explain the confusion, so you might understand the need for more accurate explanation resulting in the misinterpretation of your location.
A hemisphere just means "half of a sphere".
It is used in the terms like e.g. "northern hemisphere" and "southern hemisphere" to differentiate between a northern and southern half sphere of e.g. the earth as cut along the equator.
But using just the term "hemisphere" doesn't necessarily lead to that very distinction.
Any great circle cuts a sphere into two equal hemispheres.
A great circle is a circle with its center at the center of the sphere.
The equator and the meridians are only few examples of great circles.
