You know what really grinds my gears? When people refer to places that are north of your current location as down. As in, "We're going down to Kingwood for the weekend," or "Santa went back down to the North Pole." Is Australia called Up Over? No, it is down under! BECAUSE SOUTH IS DOWN.
Here's a map.

See the A? That's Kingwood. See the B? That's Houston. Which direction is Kingwood? WHICH DIRECTION IS KINGWOOD, SUZI?!?!? HUH? WHICH IS IT, KEVIN? THAT. IS. UP. GODDAMMIT.
Here's how you can justify down to Kingwood.

You can hold the map upside down. Except now you live in notsuoH, you're going down to doowgniK, and people say, "Hey, retard, you've got that map upside down."
I'll allow the following exceptions: If you are on top of a mountain, and the bottom of the mountain is north of you, then yes, you can go down to the valley. That is it. And last I checked, Houston was not on top of Mount fucking Everest.
