Milker (poker)
A tight or conservative player. Probably comes from the description
of someone who has to milk every hand he plays, because he would
not ordinarily get much action. To milk is to Get the most benefit
on a hand (often a hand of relatively low value) from the holder
of another, inferior, hand; usually followed by that hand or
the name of the player who was so cajoled into calling the maximum.
"You certainly milked me that time." "He milked
that hand for the most he could get, considering who he was
up against."
