>>10736835A smark is the guy who sits at a magic show and yells "Mirror under the table!" But then he goes to all the magic shows and buys merch of his favorite magicians. He thinks that by being a mark, he is supporting this artform that he claims to love but he actually makes people like it less. You see, it's already phony. And when someone points out how it's phony, it's even phonier. To the point where it doesn't make sense why they'd do it at all.
