look up any word, like hipster:
 
1.
A referee who seems curiously oblivious to walks, tons of contact, and charging when Kentucky commits them. Kentucky fans like to believe it doesn't happen, but whenever Kentucky loses they blame the referees anyway, which is ironic.

While Rupperees are a mainstay of UK basketball many UK fans deny their existence, and many rival fans invent wild conspiracy theories about John Calipari bribing refs before each game.

A portmanteau of "Rupp" (the name of the arena where UK plays home games) and "referee".
Fan: Cousins straight up mugged him inside and no foul?

Other Fan: Dude, they're Rupperees
