24 year-old golf pro Michelle Wie finally won her first major championship!

She won the US Open last weekend!

I can't tell if this is what all first time Cup winners do and this was just caught on tape and we shouldn't worry too much about it, or, is this in really poor taste, and she should have known better??

What do you think?
