P base three
A P base three is like a penis that’s still in the middle of being drawn. It’s also P base four minus one, which is the same thing but with more math and less dignity.
My brother drew P3 on the whiteboard and got in trouble for drawing a penis that was only halfway done.
A tweet said P3 is the math version of a half-decent penis drawing.
My friend used P3 in a DM to tell me he was only halfway through his morning routine.
