"Known for its periodic limited-time reappearances, the McRib — a barbecue-sauce-slathered, boneless pork patty often described as rubbery — is returning on October 7 in what is being billed as one of the biggest rollouts in recent years, appearing at more than 10,000 U.S. locations. First introduced in 1981, the sandwich inspires cultlike devotion: fans frantically hunt for it using crowdsourced trackers and celebrate its brief availability before the company pulls it again, a phenomenon likened to other viral fast-food crazes." - Jenny G.
