What's the most horrible thing you have ever done?

I did some horrible stuff when I had my affair a couple years ago. Pretty tame though by the standards of RC members, I'm sure. Not even going to expound on them really. Just stuff like pounding it out on people's desks and whatnot [/amateur]
 
The closest thing I've had to an affair was making out with two chicks at a bar, neither of which were my girlfriend of 3+ years at the time.

I don't even remember messing around with the second one, but the first one and I fooled around for a few weeks afterward. But by then I had left said 3+ year relationship so it was no longer dangerous just a little stupid instead. Within a few weeks of that, she had met her future husband and I went on to fuck my pillow and even feeling up imaginary "air boobs" on a few particularly desperate occasions.

Now she has two kids and is divorced. Time flies when you start aging.
 
well done alcohol.

so was seeing this girl who was really hot and cold with me all the time. we'd hang out, party, have sex then not talk to each other for like 2-3 weeks.

anyway, last night her and her friend hung out with me at my house. drinking begins. then off to karaoke bar. moar drinking. get back to my house. girl im seeing passes out and i end up banging the friend of the girl im seeing in the other room. girl im seeing is freaking out in the morning and won't tell me why. pretty sure she knows what's up...

go straight to hell. do not pass go. do not collect $200.
 
Ouch.
I would recommend, should it come up at some point not to try and cover it up/lie or explain it away. That's one of those things, when it happens, you pretty much just have to say "yup, got drunk and stupid."
 
okay so hilariousness right here.

the girl I was seeing tried to call us both out on it. first in the morning on their ride home together to her friend and her friend lied and said that nothing happened between us. then she asked me in a text. talked to the friend over the phone and she was apologizing for how it went down (she initiated it) and begged me not to tell her because she would lose her best friend. she also told the girl I've been seeing how we talked about how our reltionship is at the moment and how she treats me weird. she texted me and told me she wanted to apologize for how weird she's been towards me during our dating relationship! Hahahahaha.

2 girls, 2 apologies.
 
I threw a golf club at my buddy's girlfriend while she was falling asleep in his bed two weeks ago, but I sent her an apology text and she is ok with it now. Keeps cracking jokes about it
My excuse was that I thought it was him and not her
