Rounder has many meanings today, Louiebynochi is the closest to it. The Rounder term I was speaking of is a term to describe someone as a jack of all trades, but mainly they are gamblers who know how to steal and scam on the sleigh. They are into many things, but you can always bet you will find them at a card came. They know mob guys as they usually get invited to a game and are known to be good tippers when they are winning and good sports when they are losing. The ones I know anyway.
