Used to list examples; 'things like', 'and so on'.
Long explanation:
The ~だの~だの grammar point is used to list examples in a conversation, and is often used to critique or complain about something. It is a casual form and can be translated as 'things like', 'and so on' or 'et cetera' in English. The formation is simple - place 'だの' after the item you're using as an example.
