People sometimes use drunkenness as an excuse for their own bad behavior.
One time at a house party a woman I had never met before came on to me and we had sex. I wouldn't have even imagined she'd been drinking at all, let alone been "drunk".
A few days later there was chatter going around that got back to me. She was there alone cheating on her husband and was blaming her drunkenness for having had sex with me, and it was being heavily implied that I took advantage of an incapacitated person.
I wasn't really worried about it since I had a zillion witnesses who could (hopefully) support what really went down, but - trouble is still trouble, and I don't like trouble. I took the whole thing as her kind of spinning a tale as a threat in the event anyone would consider spilling the beans to her husband. I never heard about her again.
I have had sex with women who are definitely drunk i.e. let's party wooooooo! - not wasted - and me myself been drunk while doing so. But this was the only instance where anyone hinted at crying foul.
