I once played this game in college where we sat around in a circle and there was some part of the game where when it was your turn you drank and ran your finger along the forehead or face of the person sitting next to you. totally weird and WTF but I played along. it was my college friend's friend from home who was visiting who started it. We went around the circle like 6-7 times and then people were laughing and I was like WTF?
Turns out she burned a lighter into the bottom of a beer can or something and would rub her finger on that before rubbing it on my face since I was the one sitting next to her! So everyone else was fine but I had these big black lines of ash on my forehead and face. that's why people were laughing.
Pretty sure my friend told her I'd be a good sport about it.
But I never liked that bitch after that and never forgot it when she would come back to visit.
