I am functionally stealth but a long time ago I was dressed in work clothes (coveralls, boots, no makeup, hair tucked under a cap) and standing with a group of men, engaged in what one might assume to be a male activity, when a group of older teenage boys walked close by and I heard one of the boys comment "Is that a guy or a girl?" and I saw my friends' eyebrows go up. I turned to the young man and said "Whichever you are looking for, I am the opposite!". Everybody, (except the first young man) laughed out loud and the questioner slunk away with his head down.
