De mporis or in English you can't, means that you are incapable of thinking or acting smart. You can't do anything with your life or you don't know what to do with it.
Example 1:
A guy gets late to his appointment, the other guy gets angry with him and says :
-You stupid mothefucker, De mporis at all. RE.
