When attempting to urinate in the toilet pan, or urinal, the stream of one's piss breaks into two distinct sub-streams. The result of this phenomenon being that meaningful aim is rendered impossible - ultimately causing piss covered feet, yellow stained trousers or damp knees. The name is derived from the triangle formation of the streams - the angle of which, combined with the aimer's height results in a mathematical impossibility for accuracy.
Fuck, I've got an important presentation and pissangulation has caused me to wet my buff coloured strides and suede shoes - I look like an incontinent fool.
