A trial that consists of someone trying to eat ten Arby's roast beef sandwiches, usually within an alloted time limit. The contest is most regularly held in conjunction with the "Five for Five Round-up". Also known as "The Arby's Challenge".
Max made it to nine at the last Roast Beef Challenge. Then he vomited at the front of that law firm.
