bingo moment

The positive realization that a crush likes you back; unexplicit confirmation and "bingo" feeling that someone likes you and sees themselves as having a chance with you, usually through a outwardly or subtle flirt.

"Mikey got sent a winky face by the guy he likes when he invited him to a concert. No straight dude would ever send a winky face to another dude, not even ironically. So that was his bingo moment."

"When Seth told me that he liked girls with short hair, that was absolutely my bingo moment. He was smirking at me as he said it too."
