An expression of (what appears to be) regret and apology, but is actually in substance nothing of the kind.
This is an example of an unpology:
I am so sorry that that you feel that my actions hurt you in any way.
The apology here is actually a proxied apology, made in the name of the person supposedly being apologized to, i.e., apologizing for the person for the way they acted, not for any act that the person issuing the unpology did.
