Rathole (poker)
During a playing session, surreptitiously remove chips from
play. This is not strictly cheating, just not fair to the other
players who do not have an opportunity to win as much as they
might otherwise. It is not permitted in public card rooms to
remove chips from the table without cashing out. Players rat
hole chips because they don't want to chance losing them back,
or because they want to hide their winnings from someone who
has staked them or someone they owe money to.
