Mutual admiration society
A mutual admiration society was a colloquial term for two or more people who praised each other's good qualities, usually employed as a jest.

In 2268, after hearing Montgomery Scott, Leonard McCoy, and Spock each attribute the relocation of the tribbles that had overtaken  to each other, James T. Kirk pressed the issue, saying, "Gentlemen, I don't want to interrupt this mutual admiration society, but I'd like to know where the tribbles are." ()
