get gharthed

To "gharth someone" means that somebody disappoints someone several times over and over again to the point that the other party is massively resigned even after the guilty person apologizes and falsely swears to do better.

When someone disappoints you so much that you give up any hope of rehabilitation. The person breaks his word over numerous of times and falsely apologizes in the praised attempt of doing better but actually doing the opposite in the future. To "get gharthed" means for the affected party to be fully resigned of the guilty person and loose all hope in them.
