What does it mean when someone says: "King me"? [closed]

Solution 1:

It is a phrase drawn from the verb form of king that originated in checkers and draughts, but has shifted to include other games such as chess through mix-ups and misuse ("king me" does not end the game in checkers; rather promotes the piece, as opposed to "checkmate" in checkers [Source: Reddit])

12. verb To promote a piece of draughts/checkers that has traversed the board to the opposite side, that piece subsequently being permitted to move backwards as well as forwards.

I was about to make a move that would corner a piece that she was trying to get kinged, but I slid my checker back.
