突然間遇到好事情，那叫個喜出望外，就像天上掉下個大餡餅，美滋滋的！

喜出望外

1. 突如其來的好運，讓人措手不及，心情瞬間飛揚。 2. 幸運的降臨，仿佛是命運之神在暗中點撥，讓人驚喜不已。

Unexpectedly happening upon an favorable chance, akin to being smitten by a bollock of good fortune without a moment's notice. The world seems to pivot on an axis of fortunate serendipity, where serendipion and luck coalsign in an instant, that kind of zest-up-lift moment which mirrors the bashfulness of chance knocking at the door. Such moments bestow as serendipitous gifts, the cosmic nudge where destinies cross paths and serendipity graces a fortunate turn of events.

突然撞發(fā)財嘍，美得我喜歡不得了，心里跟喝了蜜一樣甜！
