A betting term for someone who continually loses at cards and makes additional side bets which cause even more cash losses
Wow, that guy was losing already and then made a side bet to lose more money! That’s additional Ham Gravy for the players!
Doing something unnecessary simply because it can be done.. Like making gravy from ham.
Dragon you should have only bought one hooker, not ten. The extra 9 were a bit ham gravy.
