Shadowmere is a horse in the game Elder Scrolls IV: Oblivion. You acquire it during a Dark Brotherhood Quest from your master and keep it for the rest of the game. It is THE fastest horse in the entire world of Oblivion. It is also a "hero" character, meaning you can't kill the thing, only knock it out.
-Holy crap! Before it took 12 hours to get from Chorrol to Cheydinnhal. But with Shadowmere, it now takes a mere 6!

A sunburn or suntan focused on the left arm. It is caused by the left side of the body being the only half that gets exposed to sunlight while driving. Presumably, it would be located on the right side of the body in countries where they drive on the left side of the road.
I had a trucker's tan after driving for 10 straight hours on a sunny day.
