That's one American Football player.
Still an example all the same though, and he's far from the only one. Hell, there's even fines for excessive celebration in the NFL and you aren't even allowed to do it at all in the NCAA, so I'm not even sure how Manziel was getting away with that save for the fact that a lot of people are on his dick. I've seen many NCAA games where players are ejected just for waving at the fans after scoring.
In the UK, celebrations are usually involved with celebrating with the people that pay money to see you. I can't understand how that can be crticised.
I pay money to see my team win, not do some stupid dipsy doodle dance whenever they score a run. I'll cheer when the ball gets hit over the fence or the puck goes into the back of the net or the WR catches a touchdown. I won't cheer when they act like idiots and do choreographed dancing afterwards.
Again, think about it this way. My clients pay me to do a job for them. When I make a solid trade and earn them a lot of money, should I have some sort of "move" that I can do when they come in for a meeting? No, because they don't want to see that. They want a return on their investment, simple as that.
