A very "butch," most likely very heterosexual (but then you can never be too sure), security guard winked at me a few months ago -- at a professional wrestling match, no less!

What happened was, I walked in and saw what was going on (this is like the professional wrestling you see on TV), and I just stood there and started to laugh. I caught myself, and then looked around to make sure no one saw me laughing (didn't want to offend anyone), and the security guy caught my glance and winked at me. Not "sexual" at all. Just a sort of "I get why you're laughing."
