In romantic terms, that practice which constitutes the smallest possible amount of dating, which can still be considered dating.
I meet Caroline on the way in to work at the same time every day, and for the smallest fraction of a second longer than would occur strictly by chance our eyes lock together, and nothing else worth noting happens but we're cool about it. I guess you could say we're quantum dating.
