The likelyhood of a guy hooking up with an "ugly" girl is inversely correlated to the frequency of sex he's been having.
Most Helpful Girl
Cause hookups are temporary which means it doesn't matter how attracted they are to the girl, as long as they get what they want and leave it's all good. When guys actually wanna settle down most are smart enough to do it with someone they actually find attractive.
I can't imagine anyone doing that if they didn't at least find you slightly attractive (enough to at least be somewhat curious). I did hook up with a girl one time that I didn't find attractive later when I was sober.
The beer goggles added about 5 points to her rating. So she was like a 4 but after a couple of dozen Jager shots, she looked like a 9. I realized she was a 4 when I sobered up, but too late at that point.
