Whilst having penetrative vaginal intercourse with a woman, usually with her on all fours in the "doggy" position, a man might suddenly transfer his penis from to her anus, without warning the woman of this sudden change. The woman's reaction is usually like that of other motorists when a driver swerves into another lan on the road without indicating: she honks loudly and attempts to stop.
"I was going away busily at this woman who was a bit loose, so I decided to take my chance, and changed lanes without indicating. You could have heard her yell in Sacramento, but boy, was she tighter there."
