When you need to piss really badly you start moving your legs and it looks like you are rapidly humping the air.
Person 1: You ok there mate?
Person 2: No I'm bursting for a piss.
Person 1: Stop Piss Humping. You're humiliating.

Just like a dog humping someone’s leg, or humping them from behind. A guy sexually abusing, or raping a male, and aren’t being brought to justice.

A very interesting and scary guy. He kind of looks like Spurned Progeny (boss) from Lords of The Fallen but he is also a platypus so he's got platypus parts. And he will hump you (only if you are a guy) if you're not careful so watch out for him when you go to bars late at night. He likes to hide in dark alleyways by populated areas. He will stalk out his prey and once he gets the chance, he will start to strip and pull a crowbar out of his rectum, then proceed to start humping the victim. BUT there is a way to prevent that. If you have a muskrat nearby, you can bait him and he will start humping the muskrat.
