When People put up Christmas Decorations way too early in the season I would call that "premature immaculation".
Fred and Martha put up all their Christmas Decorations the day before Thanksgiving... I call that a case of "premature immaculation".
Putting Christmas decorations out/up before October, let alone November.
I went to the store to get some booze and all I saw was premature Immaculation. It's September .
