A designated person at a betting-meet who retains and cares for one or more juicy sirloins that have been put up as the winner's prize.
For a long-term meat-based wager where any butchered beef might go stale if stored till the end of the betting-period, a steakholder could also mean someone who cares for one or more head of live cattle that's being offered as the prize at said later time.
