[mid-16C–19C] to cheat in cards or dice (occas. bowls), usu. in conspiracy with a confederate; thus booty fellow, one of a cheating team (also found in non-criminal senses). The result of such play is either to gang up on a third party, and share the resulting profits or ‘booty’, or deliberately to play to lose; also in fig. use; similarly used of horseracing where a jockey deliberately loses.
