Intentionally unintentional and unintentionally intentional all the time
One of my most embarrassing moments as a young freshman in college was on a blind date with a voluptuous scandannavian exchange student. She was well endowed and youthfully perky in her somewhat loose woven sweater in an age of bra-lessness. As we were being introduced and I noticed a long blond hair resting on her sweater just above her nipple. I suavely and gallantly reached over to remove the errant follicle without touching her breast to casually show how cool I was.
I was attached

She shreiked. I was totally embarassed as it occurred in front of several people. We both got over it. Being the free love era, all was forgotten by the end of the evening as we ended our date with the dance of the two backed monster.
