Tuna the Dog, a rescued Chiweenie with a distinctive overbite and recessed jaw, rose to fame on Instagram via the account @tunameltsmyheart. The specific 'Phteven' meme was born when a photo of Tuna was captioned with the name, poking fun at the phonetic pronunciation of 'Stephen' by someone with a significant lisp. The image originally went viral on Reddit and Imgur, often accompanied by a story about a Starbucks employee misunderstanding the instruction 'Stephen with a Ph.' Today, Tuna is a symbol of unconventional beauty and a staple for any joke involving lisps or awkward social encounters.
