When in a three-way, or group sex situation, when you pull out of one persons ass and shove your dick straight into someone else's mouth.
I saw the dick headed for my face, so I opened my lips. But I never would have done it, had I known it had just pulled out of someone's ass; and was in the middle of a U-Turn.

When you are with a group of people drinking, everyone says goodnight, you act like you are leaving the bar too but then at the last minute, without your friends knowing (well, maybe a couple friends know but never the whole group) you turn around and go back to the bar you just left or another bar…
We were leaving the bar but then a couple of us Irish U-Turned and we drank til 4 in the morning.
