I came very close.. at a new years party a long time ago. Got extremely hammered and passed out in a bathroom. This girl I'd never met before was offering to help me to the bed downstairs, and the next thing I know, I'm waking up to this girl trying to get me hard. I was so drunk, all I could do was sorta push her off but she wouldn't stop.
Eventually a friend of mine popped his head in and I yelled for him to help me, and he caught on pretty quick and cussed her out until she finally left.
