With all due respect I'm with Thunderheads and Matt on this one.
I don't have an ejection here. The profanity was directed at the call and not at the umpire. Now if he said You're bullsh*# I might have an ejection depending on the volume but not in this case. At 18u I think that profanity as long as it is not overused, super loud, or directed at the umpire is not an ejection.
