Steve from Yellowstone

From OAPedia.com

Steve from Yellowstone is a bit Jim Norton does whenever a boring guest is on the show. Jim takes a cell phone and calls the show from outside the studio as Steve from Yellowstone - an imitation of Steve C. Jim starts off doing an impression of Steve, and eventually degrades into Ramon insults such as "Ramooooooooon, this guy's book is dogshit!" Opie and Anthony pretend like he's a prank caller, despite leaving him on the air for so long. Jim will usually call the show again as Eric Logan, Ben from Boston, Danny from W-town, etc., and the same thing occurs again with O&A acting like they're not in on it.

Steve from Yellowstone was invented during an interview with Charles Ross who does a One Man Star Wars play. Jimmy used the moniker to call in and bash Ross from outside of the studio. [1]
