The echolocation tool men use when they piss in the dark to make sure they're hitting the toilet. This involves starting to urinate and listening carefully for the sound of the urine stream hitting the toilet water. If the sound is not heard, aiming adjustments are made until such time as the reassuring sound is heard.
Joe: "Man, I got home last night drunk, went in the bathroom, didn't turn on the light and ended up pissing all over the bathroom floor."
Bob: "You should have used piss sonar to find the toilet, bro."
Joe: "Oh."
Bob: "You should have used piss sonar to find the toilet, bro."

The foul-smelling liquid found in the bottom of a dumpster and sloshing around the bottom or a garbage truck while compacting.
Guy 1: Look at that garbage truck emptying the dumpster, and all that dumpster piss pouring out all over the place.
Guy 2: Yeah, that's nasty, kind of a greenish brown color, and smells like crap.
Guy 1: Sure does smell horrid.
Guy 2: And now its leaking out of the back of the truck all over the road and the car behind it. Poor car; that smell will never go away.

Releasing nuclear waste into outer space isn't really a proper thing to do, but it dirties the environment as much as to piss in a lake.
