Where you are so drunk that you black out and are no longer aware or in control of your words or movements. At this point, your friends move you around from place to place as they see fit, as if you were a pawn on the chess board.
"Wow, I was chess-piecin last night" - guy who was so blacked out he could not move.

"Holy shit, dude you were chess piecing hardcore last night." - friend of guy who was so blacked out he could not move.

"Hey man, we had to chess-piece you all last night." - guy who moved his drunk friend around the bar all night.
