Jhak maarna/ Jhak Maar ke Meaning

Jhak maarna, or Jhakh maarna to be more precise, means to do nothing, sit idle. And when someone says Jhak maar ke, it means eventually, finally, in a situation when you don't want to do some particular thing but you ultimately have to do it.

The two meanings here relate something like this: When you trying not to do something and due to that you don't have an option left, and you're unable to proceed with anything, you eventually do the thing.

I have tried my best here explain the relation between the two phrases, though I don't know how successful I have been here.
