Its not that I mean to eavesdrop, (or poach on anyone else's "Overheard" columns) but this convo was so odd, it needed to be shared. And this girl was talking so loudly it's as if she wanted to be heard.  Also, the exact wording may be off, as I was making as solid attempt as possible not  to hear this story:

FATTY #1: What did you do last night?

FATTY #2: I went over to Johnnies frat.

FATTY # 1: How was that?

FATTY #2: It was ok, kind of weird.

FATTY #1: How come?

FATTY #2: Well, the last time I was over there, I went back with his roommate Erik. And then for some reason, I started sucking on his fingers. I guess Erik told people, because now whenever I go over there, I'm known as the finger-sucking girl.

It's called an oral fixation. You typically grow out of it as an infant. But most likely, you were just desperately trying to get laid.
