Had one that some of my friends and I shared.

She was batschit crazy but not what you'd call a hottie.
She was 22 or 23 years old at the time and was working in the library as a intern or assistant or something of that order.

She was good for alchohol, blow_jobs and pot and she had a car.
At the time we all thought that she was pretty cool but we were all 13 and 14 years old and attending the Junior High school where she worked.
We didn't know any better, anything that was warm and wiggled was OK by us.

I don't think she ruined anyone's life that I knew of but if a guy would've been fool enough to marry her she sure as hell would have.
