adj. The characteristic word defining a moment of greatness that Jeremy Lin, an NBA player, who was undrafted out of Harvard and nearly cut three times until he was given significant playing time due to desperation for the New York Knicks. Ever since then, he has been starting every game and has been a solid player. This phenomenon is described as "Linsanity"

Hardships that he had to overcome that regard him as an underdog:
-Asian-American of Taiwanese/Chinese descent
-Harvard graduate
-Perseverance despite being undrafted and cut multiple times
-High pressure to perform well as many regard him as the face of Asian American athletics
Imaginary person: "Holy crap, did you just see that 3 point dagger against the Toronto Raptors?"

Get the Linsane mug.
The term used for rising NBA legend Jeremy Lin of the New York Knicks. He recently has led the team to an amazing 5 game winning streak, despite the absence of the star players. He also went undrafted in 2010, and furthermore was waived 2 times.

After emerging literally out of nowhere, he has become a national spectacle. His game winning drives are considered by many standards to be bordering on that of "insanity" and hence

LINSANITY
