I like to think the age of the scorer and the situation impact the celebration.
I don't mind a HS or below kid getting pumped up after a goal but when they do the same to make it 9-0 it's quite embarrassing. I also hate when a team has to get together for their group glove/head pat RIGHT in front of a goalie in a blow out. Have some class.
In adult league, there's very few times when much of a celebration is needed, IMO. When a guy that never scores actually does, I don't mind a team getting a bit loud to celebrate/bust on him. Besides that situation or a sick, sick goal...anything more than glove taps to team mates or a simple "YEAH!" is too much, in my opinion.
Adult league for me, I just point to a team mate that gave me a nice pass or made a nice play on the goal. Or laugh about how I was trying to shoot top shelf and fanned to score low.
