脾肉之叹 is a Chinese idiom (chengyu) meaning “a lament over wasted time and inaction”. Expressing regret for not being able to achieve one's ambitions or make a contribution, often due to a period of idleness. Literally, “A sigh over the flesh on one's thigh”.
During the late Eastern Han Dynasty, Liu Bei lost his territory in battles against Cao Cao and went to seek refuge with Liu Biao.
Liu Biao hosted a banquet to comfort him. During the feast, the two conversed happily.
Liu Bei went to the latrine and touched his thigh, realizing that the flesh on it had grown back. This signified a period of idleness, as a leader constantly on the move would typically be lean.
Upon returning to his seat, he couldn't help but sigh, "If things continue like this, when will I ever succeed in restoring the Han Dynasty?" His sigh expressed regret over the wasted time and his inability to achieve his ambitions.
Seeing his distress, Liu Biao then granted him territory and troops.
