"Ego defensiveness" is apparently what is behind raging soccer parents. (Nothing implied about Martin, here, it's just coincidence he's now a new dad.)
I have to laugh at the coping strategies, though. Sucking on a lollipop? Picturing Elton John? Of course, if it works, I have no complaints. I've covered enough youth soccer games to know that crazy parents do exist and it ruins the experience of participating for many.
