Linsanity refers to the meteoric and unexpected rise of Jeremy Lin during the 2011-2012 NBA season while playing for the New York Knicks. As an undrafted player from Harvard who was nearly cut from the team, Lin suddenly led a spectacular winning streak, hitting clutch shots and outscoring superstars like Kobe Bryant. The phenomenon became a global cultural sensation, transcending sports to become a symbol of underdog success and breaking racial stereotypes in professional basketball. In internet culture, Linsanity is used to reference that specific magical window of time or to describe any sudden, temporary period of absolute dominance by an unexpected person or entity.
