得寸进尺

得寸进尺

Literally means:

get one Cun, want one Chi

Actually means:

reach out for a yard after taking an inch; be insatiable

寸, 3.3cm, is a measure of length. 十寸 makes one 尺 which is equal to 33cm. The phrase literally means lusting for a 尺 after one has got a 寸, and figuratively it means being insatiable or going too far.

It also means being very greedy and never feeling satisfied. Derogatory.

寸，长度单位，相当于3.3cm，十寸等于一尺，相当于33cm。得寸进尺，得了一寸不满足，还想得到一尺。

比喻不知足，或者太过分。也比喻贪心很大，没有满足的时候。具有贬义色彩。
