Darken the doorstep
To Darken the Doorstep is when you go to someone's home and you cast a shadow over their doorstep. It usually used to describe the action of someone you know and haven't seen for a while unexpectedly turns up at your home or it's something you tell an unwanted visitor not to do ever again.

Sue: " you know the one that coursed all that trouble at my party."
Pat: " Oooh! That Jo, haven't seen her around here for ages, did you invite her in?"
Sue: " No I did not! Told her to clear off and to never darken my doorstep again."
