A term originated from a Sean Kingston song bearing the same name. This is the action of being awed by the fact that someone who you originally underestimated turned out to be your true love.
"And now I see your face drop, I told you not to leave me alone and now that I got my own, I see your face drop, I told you not to count me out"
After being rejected, Sean's sought after girl had a face drop upon realization they were meant to be together.
One who is truly accomplished in the street dance form known as krumping.
