What does "good job" mean? [closed]

What is the meaning of "good job" in English? I have heard some people use that instead of "do not be tired".


Solution 1:

The phrase is commonly spoken to one who has done something worthy of praise. For example, if a sales representative brings in $10 million on a deal, his boss may tell him that he did a "good job." In this sense, the definition is quite literal.

However, "good job" can also be used in a sarcastic tone. In this case, the recipient is being mocked for something he has done poorly.
