I hav heard this many times, but never found a single example - and I’ve looked. Everyone I’ve researched on the registry richly deserved it.

I challenge you and anyone else reading this to find an example of someone who is on the sex offender registry due to public urination.

I had a friend threatened with this by a cop. I was there. We had been drinking and he wanted to change his oil at a Jiffy Lube. Unbeknownst to us there was a park on the other side. He just got a ticket but the cop made the threat. It doesn't disprove your claim but it is an example of why the belief might persist

It's a stupid meme. Public urination, like actually taking a piss in public while no one is around you, is likely going to be a ticket for disorderly conduct if a specific charge for it doesn't exist. You won't get an indecent exposure charge unless you're purposely exposing yourself to others, it requires intent. Sometimes flashers will use the excuse of urinating for their intentional exposure or will lie that their indecent exposure charge was due to public urination and not because they were really masturbating in plain view. There probably have been prosecutors that have tried to slap an indecent exposure charge on an innocent public urinater but like everyone else says, they can't find any proof of it actually sticking.
