the act of praising yourself or saying how well you have done something

Such writing comes uneasily close to self-congratulation. 这样的行文近乎自我祝贺，让人生厌。

Congress and the president indulged in a round of mutual self-congratulation over their agreement on a package for the new fiscal year. 国会和总统就新财政年度的一揽子计划达成协议，对此他们让自己沉醉在一轮相互的自我祝贺中。
