Morphology
The parts 'what's' (= what is) and 'with' (marking association or regarding) give a partial clue that the phrase asks about the reason or state of something, so a learner who knows the words can often guess the general function. However, the colloquial pragmatic use (e.g. expressing mild annoyance or puzzlement) and the specific grammatical pattern 'what's with X' are idiomatic enough that full understanding and appropriate use typically require prior exposure.
Etymology
What's with comes from asking what is happening with something you notice, like seeing a messy room and saying what's with all this because you want a 'reason' or feel a little annoyed. So, it's used to ask for an explanation or show mild annoyance.
