Ever be cruising along at a speed that actually gets you somewhere in a limited amount of time (unless you get pulled over) and have some jackass who's on the cruise control and putzing along slowly to use less gas get in your way? Those bastards are hypermiling, which is the lowest form of dorkiness--yes WoW geeks, you just moved up a notch, but don't let it get to your head, and no you didn't just level up. Anyway, those morons drive slow, tailgate, occasionally run red lights/stop signs, or even turn the engine off and cruise! All to save a few ounces of gas. Oh, they usually have a bunch of annoying bumper stickers all over the back of their cars (often none are on the actual bumper, aparantly they didn't understand the concept). If I'm going to be stuck beind some 1984 VW Golf diesel, I expect to see black sooty porn and not black sooty propaganda.
What's worse is that the nerds who write the OED, who are one notch above WoW players and two above hypermilers--unless they happen also to be in those other groups, decided that hypermiling is the word of the year. Kinda jumping the gun in mid November, eh? Anyway I was rooting for schadenfreude, which is my favorite word. I suppose it's not the end of the world, as I know sooner or later I'll be hypomiling (my word of 2009) and I'll get to watch some hypermiling jackass rear end a semi they're tailgating while their engine is off and their power brakes aren't so powered. Then I'll roll down the windows (keeping my AC on) and yell, SCHADENFREUDE! Don't think they make any hybrid hearses, nor have I ever seen any with any bumper stickers.
