Yes, and we coaches walk through the line up too. I've heard girls drop the "B" word and "F U".
What we have done the last couple of years is to invite the line up into a end of game prayer circle. I'm not pushing religion on anyone, but it has been very successful and seems to tone down any harsh feelings about the game. We only had 2 teams in that time refuse.
I have seen such things, though never in college. I would suggest that all the adults in the room, or kids lives have taken a sabbatical from "class"; as in class act! When kids start this stuff at say age 12 and no one objects, especially their adult supervision or parents, it will only get worse. Spank the kids but don't forget to spank the adults too!
