What's your best/worst "Oh you didn't know moment?"

I was at a friends house once and to set the scene were all drinking in the front room. It's common knowledge to everyone in the room initially that I'd slept with one of the girls, let's call her C, what everyone didn't know was that me and another of the girls, A, had also slept together, only me and A knew about it. That's not too bad.

Then, B walks in, a girl Id had a one night stand with. Now I'm sat in a room with 3 separate people I've slept with none of which know about the others except A, and everyone else, knew I'd slept with C.

To my horror, a drinking game of I Have Never ensues. I tried in vain to slip out of the room but I was shouted down because I'm always a good sport and have good stories. I lose and end up drunk essentially because of all the dumb shit I've done. I prayed and prayed and prayed no one would say anything but someone says "I Have Never slept with someone in this room."

I had to drink, because everyone knew I'd slept with C. Some couples in the room drank. A and B also drank. In my friends version of I Have Never, we have a wild card rule, where each player gets a Story Card and if someone drinks to something and you want to know the details, you play your story card and the person has to go into detail as embarrassing as the details might be. Then some evil person, let's call them D, plays their card on B, who wasn't a regular of the group, she spills the beans about sleeping with me, not knowing I've slept with two other girls in the room, both of which turn to look at each other and me and everyone clocks on and a lot of details I'd have rather kept quiet come flying out.

I took a long swig of my drink and said meekly "Oh, didn't you guys know", and was tortured about it for months

TL;DR- game of I have never revealed I'd slept with three people all in the same room and they didn't know
