Fly on the wall

When a male does a headstand, naked, against a wall and his penis and balls resembles the facial configurations of a fly or mosquito. You can also flail your legs to make it look like your fly has arms. Like a wacky, waving, inflatable, arm-flailing tube man.

My son keeps doing the fly on the wall whenever he gets out of the shower.
