There is a song which has this phrase:
What time do you call this?
repeated in it. Is this a phrase with special meaning?
Here is a link to song
It means: "You are very late!" When a 16 year old girl returns home at 02.00, her parents will say to her: "What time do you call this?!Why are you late?
This type of question is called a rhetorical question, which is asked to make a point rather than to elicit an answer.
If you were to say to a 16 year old girl "Why are you late?" the girl will come up with a long list of (in her opinion valid) reasons, and a family dispute will probably follow. I witnessed many such disputes between my father and my younger sister.
So, what you do instead is to ask a question that can't reasonably be answered:
"What time do you call this?"
An argument may still ensue, but the parent has (or at least think they have) the upper hand after asking this kind of question.
