Once. A bar closes, we all walk out at once. A hefty sized woman was making very aggressive remarks to my brother, talking about taking him home and having her way with him, etc. My brother was pretty bothered. I simply said he wasn't interested while I was trying to hold back a laugh. She immediately took offense and got in my face yelling how much of an asshole I am. I tend to laugh and smile while I'm nervous and I'm still smiling and backing up while holding my hands up in a non-aggresive manner and trying to apologize. The entire time her friends are trying to stop her because she's a drunken mess. I eventually back into a car and have no where to go. She slapped me hard enough to bust my lip and (I think) some stranger shoved her and she took about 4 or 5 steps before tripping on her own legs and falling like a sack of bricks. Her friends apologized to me and they left. Of course the cops grab me because there was a commotion. Luckily, several witnesses came to my rescue and some people even had videos. Went to IHOP (ihob?) after and someone anonymously paid for my breakfast!
