The following is a true story. I repeat. The following is a true story. I mention that twice because you won’t believe this actually happened. So fasten your seatbelts. Oh, and you might want to grab a moist towelette in case you feel woefully unclean once you’re done reading. A must read: http://sportschump.net/2015/03/24/operation-bruin-puke-spent-sunday-amalie-vomitorium/15251/
Chris - In actuality there's a third lesson to be learned from your story: Never, and I mean NEVER, listen to any advice offered by your waffle fry friend in the future. He might as well of given her some Ipecac. And I hope for your sake, and sanity, that a crummy video of this from 20 rows up doesn't appear on YouTube.
Perhaps you are blaming the wrong catalyst for her puking. I instantly throw-up at the sight of a Bruins fan. No alcohol or waffle fries necessary. She may have been so drunk that she didn't even realize what was going on around her. Then the waffle fries sobered her up just a touch...thus leading to the puking.
