Esnupi is a viral linguistic variation of the classic Peanuts character Snoopy, stemming from the phonetic spelling often used in Spanish-speaking internet circles. The meme typically features a low-fidelity or classic illustration of Snoopy, often accompanied by 'good morning' messages or simple, heartwarming phrases that straddle the line between genuine sentiment and ironic 'boomer' humor. Its popularity peaked as a reaction to overly formal or sincere social media posts, evolving into a mascot for chill, low-stress interactions. Today, Esnupi is a staple in Latin American meme culture, used to express everything from wholesome morning greetings to existential calm with a uniquely internet-era twist.
