The 'I Herd U Liek Mudkips' meme is one of the internet's earliest and most enduring viral sensations, originating on the 4chan imageboard in late 2004. It began as a catchphrase used by members of the 'Mudkip Club' on DeviantArt before being adopted by /b/ users as a form of greeting or nonsensical spam. The meme typically features the Water-type Pokémon Mudkip from Pokémon Ruby and Sapphire, paired with the intentionally misspelled caption. Over the years, it evolved from a simple inside joke into a symbol of mid-2000s internet culture, frequently appearing in webcomics, flash animations, and social media threads to express mock enthusiasm or random nostalgia.
