I am known for having an eye twitch when people call what comes out of volcanos "smoke." They make it a point to point it out now. Someone says, "hey, the crater is smoking", and someone else will say, "Look out, pod's eye is twitching." So, I have a reputation of being pedantic on this subtle, but important, distinction. Or lava verses magma. It's just one of those things that gets under my skin, and it is hard to keep my mouth shut. And I keep it shut more often than not. Especially in real life social situations. Correcting basic scientific errors just makes me come across as an annoying asshole. So, I bite my lip and let it go. But there are times it is just so bloody difficult. Due to the internet, this has become more difficult. Friends will ask my scientific opinion about a youtube video they watched with some ridiculous claim about Yellowstone, or the earth's rotation, sunspots causing global warming, or some damn thing, and it almost breaks my heart to tell them they have been lied to. Their face falls and their eyes glaze over as I try to describe the difference between the earth's magnetic poles and the rotation poles.

My intro geology prof was brutal about this sort of thing. He charged a six pack of beer if you used "rock" instead of "mineral." He drank a lot of beer.
