[Idiom] Looking for idiom meaning to lose a tail

[scobbe502]

Hey guys,

I'm not totally sure, but I thought there was an idiom meaning to lose a tail (like a car following you). Does anyone have an idea which idiom I'm talking about? Any help would be greatly appreciated.

Thank you!

You shake a tail. Or you shake off someone that's following you.
