I had many when I was younger, but the only one that REALLY embarassed me was fairly recent.
About 3-4 years ago Brian and I went to his cousin's wedding. This was my first time meeting Brian's extended family. I quite honestly, am not a big fan of weddings, but I LOVE open bars. I hadn't had anything to eat alllllllll day and for some reason thought hitting the open bar and stuffing my face with greasey buffet wedding food would be a good idea. NOPE. After about 12 mixed drinks the whole room started to spin. I stumbled my way to the bathroom which was full of people - mostly guests at another event that was going on in another part of the venue at the same time. Every stall was full. But I couldn't hold in it in. I threw up ALLLLL over the floor of the crowded ladies room (which quickly cleared out after I barfed all over the place). Not only did I vomit, but I vomited chunks of food. Like strings of linguine spewed from my mouth. I got it all over the floor, my shoes and my dress (that my MIL bought me for the wedding). My SIL walked in and goes "Um, Jess, are you ok?!" To which I answered "I think there was something wrong with the food." Haha. yes,in my drunken state I totally tried to deny I was drunk and blame the caterers. I'm an ass I managed to somewhat clean myself up.
Yeah, great first impression I made on Brian's family. Lucky for me the grooms father was also SMASHED and made a really embarassing toast so that pretty much became the talk of the wedding and I was able to slide under the radar despite having the distinct smell of barf on me for the rest of the night.
