Dr. David Livesey is a character from the 1988 Soviet animated film Treasure Island, which gained massive internet fame decades after its release. Known for his exaggerated physique, relentless optimism, and a distinctively wide-striding 'sigma' walk, Livesey became the face of the 'Phonk Walk' trend across social media platforms like TikTok and YouTube. The meme typically features the doctor confidently marching alongside his companions, often synchronized to heavy Phonk music like 'Why Not' by Ghostface Playa. It represents peak confidence and a carefree attitude even in the face of danger, and is frequently used to depict someone entering a room or situation with undeniable, overwhelming swagger.
