TTUN 

TTUN stands for "That Team Up North". The phrase was used by Ohio State football coach Woody Hayes to refer to archrival Michigan. Similarly, TSUN stands for "That State Up North" or "That School Up North". Ostensibly, Woody hated the Wolverines so much that he could not bring himself to say their name. Today, the acronym is similarly used online by Ohio State fans.

I hate TTUN so goddamn much
