here are a few examples: http://de.wiktionary.org/wiki/br%C3%BCskieren

To be honest, I have never heard of this word and I am quite eloquent in my mother tongue. So I don't think it will be understood even by natives. However it's possible that it's just not used in my region but still, you should stick to "beleidigen" it is much more common and there is no reason not to use it.

Ich brüskiere mein Vater mit mein Verhalten.

It means something like "to snub" however as already mentioned we don't use this word in Germany very often. It is often used when someone did something unexpected wrong without showing regret. But i would recommend you to use "beleidigen" because it means nearly the same as "brüskieren".
