Nando's is a peri-peri chicken restaurant chain with a large following in the United Kingdom, where cheeky Nando's became a familiar piece of everyday slang for an impromptu meal with friends. The phrase spread through social media captions, group chats and short videos, where it was used to frame an ordinary dinner as a small, enjoyable indulgence. It has stayed in use because it is short, instantly recognisable to British audiences and flexible enough to fit lunch breaks, celebrations and post-work meetups.
