First of all stop being a baby and stop acting like you've never heard the word fuck before. The dude is almost crying telling security on Westbrook, he said the word fuck to me and my wife. Grow up.
Secondly if you're an opposing fan trying to get under the skin of a player they might use big boy language in their response. I'm sure there were some Mavs fans throughout the series that said worse things to Westbrook.
The good thing for Westbrook and the Thunder is they don't have to deal with the Mavs or their butthurt fans anymore.
