gut buster

Yet the constancy of the chain's two-ounce square burgers has bred fierce loyalty among some customers, who have affectionately nicknamed them "sliders," "belly bombers" and "gut busters."

There was also a "gut busters" calisthenics session at 8:30 A.M., and, at 9:45 A.M., a group walkathon.

They appear in the show "Big Eats" on the Food Network and on March 3, star in "Gut Busters," a documentary about the competitive eating circuit, on The Discovery Channel.

White Castles open 24 hours a day have long been a siren for off-kilter customers looking to cap off their evening by gulping down sodas and devouring Slyders, the restaurant's signature burgers, also known by some people as murder burgers or gut busters.
