It was almost 10 years ago and I'd say 8 of those years were my good drinking times, so it's not crystal clear. Basically it started with the girls getting tipsy and one of them said something followed by immediate silence and a tense stare at me I'm guessing to see if I heard anything. It was something like "Oh, THAT party. The one where you..." That's not it, but pretty close. So anyway, they got sloshed and kept acting like little slutty drunk girls will sometimes, and the girl I was dating made a comment about her friend hooking up with anything in site when they were in Mexico, to which said friend said, "Well, at least I never got gangbanged in front of a party!"
*awkward silence, all of the blood in John's body flows to his ears, jaw clenches tight enough to make a diamond out of coal*
There really wasn't any recovering from that one gracefully. They were drunk like the chick in 40 Year Old Virgin.
