Has anyone heard of the "copulatory gaze"?

I read about it in a couple of articles I found and apparently it's the one eye contact that indicates certain attraction, especially if the pupils dilate.

I remember this gaze happening with this girl I like. We looked at each other several times for at the very least 2 seconds. We would smile at each other then look away.

Do you guys believe in the "copulatory gaze"? or not

Do you think this girl likes me back?
