Meaning of MASON in English
A master bricklayer, one who has made plans with friends, family, members, or co-workers without following through with what he says he will do so many times it boggles his friends' minds. Example: I've called Gootermin every weekend for the past 6 months. He always says he will come to the pub for a round or two but never shows. He's beyond a bricklayer--this guy's become a full fledged mason.
