masterbask 

When no one will give you the gratification of a job well done, you are forced to masterbask in your own accomplishment.

No one would give me the credit I deserved for a great project at work, so I was forced to shut the door to my office and masterbask.

I had just finished painting the bathroom and showed my wife, she said "fine" but you have more work to do. I needed to masterbask in my accomplishment. Then I felt better.
