Iván Tapia is known online for this catchphrase, which combines wákala, a slang expression of disgust in Spanish, with huele a yerba, meaning it smells like weed. The short recording circulates as a shareable audio among Spanish speaking users, who reuse it as a quick punchline whenever something smells bad or seems suspicious. Its popularity comes from the recognisable voice and the specific wording, so even without context listeners understand the joke is about exaggerated disgust rather than a literal description of the scene in front of them.
