Reader Moderniste had a run-in with some huge nuts on the 22 the other day, and wrote about it on Violation Report:
The bus was full, and I really needed to sit down. And this prince of a guy was “saving” the last available seat for his apparently HUGE testicles.
Bravely, I tried to wedge myself into the 8 inches of seat left, thinking that my difficulty in trying to sit down would clue him in to moving aside a bit. (And mind you, I am a very thin person.) Alas, this Alpha Male cared more about his outsized genitalia than my comfort. So I stood back up and snapped his picture 
Thanks, M!

I’ve seen that guy walking down Mission before, he’s got a thing for wearing bike shorts. Pretty much everybody on the street was distracted by him.
“Big ol’ cock’n'balls, wasn’t it?” remarked another pedestrian. “It doesn’t make you gay to notice it,” he said.

Just gotta sit down and pour on the “excuse me” and gently push his leg out of your space. Glaring might be called for. “Dude, seriously?” also might be necessary.
I live in NYC. Welcome to my world. Sorry to see that this BS has spread back to my home town and love of all loves SF.
