What is Hibyer?
1.
hibyer, n. (hi+bye+suffix er)
a marginal acquaintance with whom "hi' and "bye" are the most typical units of verbal exchange; the vocabulary of a minimal relationship.
Do you know this woman? - Not really, we are hibyers.
They were married for ten years, but now they are only hibyers.
I was surprised when hibyer stopped for a more substantial conversation.
