Here's this week's most outrageous relationship red flag story from the editors of The Little Black Blog of Big Red Flags.

The Story: "My best friend met a girl online off some random dating site. They went out on a few dates, and he was hooked. When I got to meet her, I could kind of see why: She was gorgeous.

But she was also the type of girl who dressed skimpy every single day (red flag). We're talking extremely tight tank tops and mini-skirts with a bit of her butt hanging out.

Against his better judgment, and the judgment of his friends, he eventually let this girl move in with him after she got into a bit of "trouble" with her ex-boyfriend (red flag). What made this worse was that my friend was only 21 and lived at home with his mom, dad, two younger brothers and two dogs.

The biggest red flag regarding this chick came shortly thereafter when we were all out at a bar.

A group of other guys started hitting on her. She made out with two of them, gave a lapdance to another and then said she wanted to go home with this group of random horny dudes she just met. (Four, five red flags, at this point?)

Despite the rest of us trying to save her from a probable rape, she went anyway. She came back the next afternoon feeling bad for what she'd done. So, she offered my friend some pity sex. After they were done she told him she didn't want to be his official girlfriend.

This has all happened this past year ... and my friend is still crazy about her."
