When one approaches a no U-turn sign, but must turn around regardless, so they make a left into a parking lot and go around, forming a D.
Girl: Fuck i missed the restaurant and i can't make any U-turns on this road!

Guy: Just make a D-turn.

Girl: wtf is a D-turn?

Guy: DAMN LOOK IT UP ON URBAN DICTIONARY. MUST YOU SUCK AT EVERYTHING?
