ungreetings 

A further synonym for goodbye or farewell.
Both and interjection and a noun.
The direct antonym of "greetings".
Derivation: A more logical way of bidding someone farewell, one begins by greeting a person and then does the opposite upon departure, thus the prefix "un-" is used as means of implying the antonym.

Ungreetings (noun):
It’s time to say ungreetings and catch the plane.

Ungreetings (interjection):
Ungreetings my friend, i must be off.

unparenting 

Term coined by me, Hannah Herbst.

When someone, usually another relative or a parent themselves, sees a particular parent's approach as unfit and sees the need to do things differently, undermining the parenting process of the actual parent.

Ex:

Mother: "I'm going to smack that kid for doing dishes!"
Uncle: "No you WON'T."
Mother: "It's my kid!"
Uncle: "It doesn't matter. (looks and says to kid) Kid, you don't have to do dishes."
Mother: "STOP unparenting my kid!!!"

Kid no longer listens to Mom about dishes. Mom's parenting abilities have been reduced!
