だの

だの goes after each item in a list of examples – "A, B and whatnot" – and tells the listener you are fed up with them. A noun or a な-adjective takes it directly; a verb or an い-adjective takes it in the plain form.

When the items are things someone says, the last だの often takes とbefore ゆう言う or a word like うるさい or もんく文句.

Contradictory pairs

An item and its opposite with だの mock someone who can't decide.

だの or とか

とか lists examples neutrally. だの adds annoyance or contempt, so it doesn't fit a sentence that is simply giving information.

だの belongs to speech and informal writing.
