What should I do to intimidate a chick who's after my girl?

We call her the "boob chick" cuz she sends pictures of her boobs to my girlfriend. My girlfriend is cursed with too much kindness and refuses to be firm and send her away, because they were childhood friends.

I'm not worried at all lol my girl and I are completely solid for life... but for kicks, I wanna seem really scary to this woman when I go to the bar tonight (where my girl works). Boob chick is going to be there and I want to intimidate the h3ll out of her ;)

I shall be riding my Ducati Monster 696 and wearing full leathers, with a vest and nothing underneath ;) I have already decided lol anything else? Things to say? I'm gonna drink Jack straight like I always do, so I figure that might make me look good ;) hahaha

I'm a chick btw. And my looks have been compared to both, Lzzy Hale and Kate Moennig... so how shall I use this? Lol

Just for fun, though! Nothing too serious.
