first time as an adverb meaning "for the first time"?

Question

Can **first time** be used as an adverb meaning "for the first time", e.g. *when I met him first time* (Confession Tapes, third episode, 02:40)

Answer 1

This does not sound grammatical to me in formal spoken English. It might be acceptable in a spoken dialect. In formal spoken English it should be "for the first time."
