An erection fueled not by arousal but rather the insatiable urge to urinate.

A young male who, on the surface appears to have it all together, but behind the scenes is a total trainwreck of a human being with no regard for civilized society or social norms.
Dude I woke up with a raging pissbone this morning, but then I took a leak and it was all gone.

That party was fun until those Pissbones left hot pocket crumbs all over the couch and started a "chug" chant.
