The 'Right Proper Lad' meme stems from a specific dialogue exchange in Game of Thrones Season 7, where Ser Davos Seaworth describes Jon Snow. The internet quickly latched onto the earnest yet slightly repetitive phrasing, turning it into a versatile template for expressing both genuine and sarcastic admiration. It is primarily used to validate someone's character or actions, often paired with an image of Jon Snow or Davos looking stoic. The meme's popularity peaked on Reddit's r/freefolk subreddit, where it became a staple of 'proper' fan culture and character appreciation.
