莫装逼装逼遭雷劈莫装纯装纯遭人轮
[mò zhuāng bī zhuāng bī zāo léi pī mò zhuāng chún zhuāng chún zāo rén lún]
A somewhat harsh expression warning people not to be arrogant because overconfidence often leads to embarrassment; similarly, one shouldn't pretend to be innocent all the time as no one would believe in such fake purity. This indicates a desire to avoid these types of behaviors. The term '遭雷劈' (zāo léi pī) means struck by lightning. And '遭人轮' is a vulgar phrase implying punishment or rejection, better translated loosely.
