How do I explain this behavior ?

I go to the club every week on saturday hoping to get laid. But I have never gotten laid. So I gave up and last week I went to the bar not to get laid but to enjoy a beer and I had exactly one beer cause I was broke. I also was shabbily dressed compared to all other days I go there. I went and sat with the college jocks who apparently where not too amused by this for some reason. But their spot was a good vantage point so I went ahead and sat there anyway.What surprised me was I had girls flocking to me like moths to a flame. Four pretty girls asked to dance with me on separate incidences I said no all four times(dont dance went I am sobber) . Usually I have girls refusing to dance with me. I have been to the club sobber before and no girls came to me.
