Not exactly sure if you came to the right place to ask about fights

Either way, fight or don't fight, go out with pride, yeah? Personally, I don't know if he's worth your effort or energy, but whatever. A fight is a fight, with your fist in his face. =]

EDIT: If it's to intimidate that you want to do, throw in a few cusses, or don't say anything at all. It's not the words that intimidate someone, it's the words that provoke someone. If you really want to intimidate him, stay quiet, and SHOW that you wanna rip his throat out... but don't try too hard.
