Waving the arms, "T" or not?

[HoosierBuckeye Ref]

Oh wait...

Last night in my intramural game, I was trail and called a foul up between the foul line and the arc and called it on the floor. I stepped in yelling "on the ground" and waving my arms to call off the shot.

Player then procedes to start waving his arms mocking my selling of the call. Bam, T.

Might have been the same kid who chased me off the court . . . even though he won.
