Ugly girls..Horny guys? why?

So here's the situation...I know at least some of you must actually date so I'm asking for an opinion (rants and insults aside) I dated someone for like 2 years and broke up with him for all the right reasons...well after him being single for a long long time. He gets a gf and doesn't say anything to anyone..The odd thing is this particular girl he makes fun of all the time...shes hideous, fat, tall and just plain bleah! and he made jokes about him resembling his manly mom (who's also a psychopath)...I think i really pity him...obviously he's embarrassed of her but then why did he ask her out? Are some guys so horny that they'll date anything? :\ I mean a paper bag over the head is one thing but you'd need a body bag for her...Feel free to share your horror stories...who/what have you done in desperation?

i said opinions (rants and insults aside) is that so hard to understand? is it?? i wouldn't post this if she was a good looking girl and i was looking on input from what you guys think is a good reason to date a really ugly chick...and if you want to know about me so badly why dont you ask in the right way? This wasn't about how i look so send me a link to your pics and then we might talk.. and 4chan guys wonder why they're virgins and/or single...you must be gay
