Kaepernicking is a viral photo fad named after former San Francisco 49ers quarterback Colin Kaepernick, which involves posing while kissing one's bicep. The trend took off during the 2012-2013 NFL season after Kaepernick began using the move as his signature touchdown celebration. It gained mainstream popularity as a rival to 'Tebowing,' with fans across social media posting photos of themselves mimicking the pose in various locations. While originally a symbol of athletic confidence and victory on the football field, the meme evolved into a general expression of self-celebration and triumph, often used to mock opponents or celebrate personal achievements in a lighthearted, swagger-filled way.
