When you’re friendly with your neighbors to the point of saying “Hey” or waving. Not a friendship or a close neighbor, but just enough to acknowledge each other’s existence and be polite about it. Typically you really don’t give a damn about them, but you also don’t want to be rude.

Alternate spelling can be “Heyborship.”
My neighbor George and I wave and say “Hey,” but we never hang out, so our relationship is just a Heighborship.
