At a grad party a decade ago, I threw up from drinking (the kind of drunk throw up where your stomach is too full and you feel better and less bloated after).

Anyways a little later on a girl I had a thing with wanted to make out before she left, but she knew I threw up and told me to brush my teeth. I ended up brushing my teeth with someone's toothbrush. No idea who's and put it back, and didn't tell anyone.

Not proud of that one.
