Isosceles Triangle 

When you have a raging boner and have to piss at an angle over the toilet while supporting yourself with one arm, and thereby forming an isosceles triangle.

"Man, I woke up with a piss -boner today and had to lean over the toilet while holding myself up on the medicine cabinet. Talk about an isosceles triangle!"

Guy 2: Yeah last night was rad dude. Those spare doritos were worth it.
