The act of a person being hit on the button. Usually the chin or behind the ear. Then going unconcious.
I saw a mma fight and guy got hit hard on the chin by a punch. He dropped and layed on the ground frozen for about 20-30 seconds. He got knocked out cold.

"Patient X was not outside when I called his name."
"He's out went cold."
