The 'Shalissa' meme originates from a viral 2013 Vine video where a young woman is shown a photo of what appears to be Beyoncé. When asked 'Who is that?', she confidently identifies the person as 'Shalissa.' When the confused cameraman asks 'Who's Shalissa?', she delivers the legendary punchline: 'Me, nigga.' This meme became a hall-of-fame Vine moment, celebrated for its perfect comedic timing and the girl's unshakable confidence. It is frequently used to reference alter egos, situations involving mistaken identity, or simply to express a high level of self-assurance.
