The reason it looks fake, is a woman's stream wouldn't arc like that, while standing upright. Even then, a man would only pee straight outward, when they possess a tiny penis that can't hang naturally due to gravity; shrinkage, possibly permanent, due to estrogen supplements, or temporary, having just gotten out of a pool (see: Seinfeld s5e21, "The Hamptons"); simply being engorged, and unable to piss below horizontal (see: morning wood); or perhaps because they are in fact holding and aiming the tallywacker, as can be seen in this example, for maximum distance.
