Fratpack,

I think you hit on an important point..."angle of your aim."

In my experience, guys with longer schlongs tend to point "downward" into the presumably larger pool of urinal water...

Guys with tiny little stubs are pointing "ahead" toward the back wall of the urinal.

So when I am in a stall and I hear an almost-silent stream, I imagine a tiny little dick that's barely pulled out of the shorts. Conversely, if I hear a heavy stream, I assume there's a giant cock hanging downward and unloading into the water more forcefully, making more noise.

Whaddya think guys...a valid point?
