Nagging is the repetition of unpalatable truths.
Behind the line
What it means
Our interpretation.
The speaker redefines nagging with a pointed twist: it is not pointless complaint but the same true things said again and again. Those truths are unwelcome, so hearing them repeatedly irritates. The quip suggests the annoyance lies with the listener's discomfort as much as the speaker's persistence.
