This commercial amused me so much. Puffery is one of those terms that when you first hear it, you assume you misunderstood because it couldn’t possibly be a real legal term. But it is. Basically, puffery is exagerated praise for promoting or selling products. E.g. “The Godfread Law Firm is the greatest law firm ever!!!” The legal effect is that you couldn’t sue me for deceptive advertising or breach of warranty or otherwise rely upon that statement.
