It looks like the fan that Rick Pitino allegedly flipped off is telling everyone he can that it really did happen.
Here are a couple of tweets from his account with the first one being after it happened:
#UK beats #UL & I gladly remind Pitino of his record vsCal @UK of 1-8 as he leaves the floor. He disapproved & flipped me the bird! #DayMade

Mark it was not a fist pump. He flipped me off.
