This athlete did a great routine. However, it seems that some people cannot/will not "read the room". What is acceptable behaviour at home is not always acceptable elsewhere. Please consider your hosts and take your lead from them.
Maybe put a bit of thought about different cultures in it before you go somewhere else and then get disheartened and badmouth local people because they dont act like americans?
The nervous wreck (but seriously the last time I went for competition I was freaking out that tears of fear rolled down my cheeks before the first event)
