Imagine hating a neighbor so much that you'd make a sign about them so big ALIENS could see it.
Someone was looking at satellite images on Google Maps, and found a plot of land in Salt Lake City where someone mowed a rude word into a big patch of grass.
They spelled out the B-WORD on an empty plot of land behind someone's property. And they added a giant arrow pointing directly at that house, just to be clear who they were talking about.
We don't know when they did it or if it's still there.
