Insulting is the wrong word, there is a fine line between "Cocky & Funny" and "Cocky & Arogant", its easy to confuse these two, but if you're insulting her, you're doing it wrong.
I for one really like DeAngelos way, its fits me. Remember, different styles fit different people. And when you are practicing being Cocky & Funny, you will screw up, everybody does at the beginning, so don't take it too seriously
It takes time to learn to stay on the funny side and not ending up being the arogant bastard
