nod of acknowledgement 

(supplementary) The *upward* nod of acknowledgement has quite different connotations to the *downward* nod of acknowledgement.

The user of the *upward* nod of acknowledgement displays the nostrils and their contents to the subject, whilst symultaneously looking down on them. It therefore signals disrespect.
The *downward* nodder looks up to the subject, displaying submission to them. It therefore signals respect.

Acknowlogize 

Or "Acknowlogy"

When one doesn't actually apologize. Instead, they acknowledge that they have done wrong without actually saying sorry. Or someone trying to make you laugh after they realized they upset your feelings. They know they made a mistake, but use jokes and/or gifts as a way of saying sorry.

"Rather than my husband saying sorry, he acknowlogized by giving me flowers instead"
