You think truth or dare is bad... We once met a couple at there house and we started chating etc when I got up to go to the toilet the husband said when you get back we can play couples "Finger-Board" me being a pervert and with the language Barrier between us I thought he meant that we were going to finger each other's wife's until we got board!
When I came out of the bathroom there was a table in the middle of the room with an actual finger board. I immediately realised how sober I was and wanted to cringe. They had made up there own sexual Finger-Board game...
Cutting one short story long, thanks to our "make the best of any situation" attitude and with the help of tequila we ended up beating them at there own game and actually have a good session.
Just hope we never have to do that again...
