The 'What's the Matter, Lagerboy?' meme originates from a classic 1990s television commercial for Boddingtons Bitter, an English beer. In the advertisement, a group of rugged, traditional ale drinkers mock a newcomer for ordering a 'cold, refreshing lager' instead of their hearty bitter. The line 'Afraid you might taste something?' became a famous catchphrase, highlighting the humorous elitism often found in niche subcultures. Today, the meme is used to gatekeep or jokingly criticize anyone choosing a mainstream, 'diluted,' or easier version of a product, hobby, or lifestyle compared to the more intense or traditional alternative.
