The Spider-Man Triple meme is an evolution of the classic 1967 'Double Identity' cartoon episode where two Spider-Men point at each other. The three-way version became a viral sensation after 'Spider-Man: Into the Spider-Verse' and reached peak popularity when Tom Holland, Andrew Garfield, and Tobey Maguire recreated the pose to promote 'Spider-Man: No Way Home'. It is typically used to represent a standoff where three parties are equally guilty, confused, or identical in their behavior, making it a staple for internet call-outs.
