Meaning & usage
とか presents one or more items as vague examples from a larger set, with a nuance like for example, or, or something like that. It follows nouns and the plain form of verbs, adjectives, and clauses, often in the pattern AとかBとか, and can combine with なんか or という to increase vagueness. It is casual and common in speech, so や or たり are safer in formal writing, and it can sound dismissive when used to refer to people who deserve respect.
