What would you call?

[Junker]

I would be in agreement that the T would be well deserved, but depending on the game situation couldn't you talk to the kid about his body language? If this was the first sign of trouble in the game I think I would be apt to tell the kid to watch his body language as it very well could be viewed as unsportsmanlike. Then he's had his warning and is on the short leash for the rest of the game. Just a suggestion.
