Is the use of 'has' appropriate with first person singular?

Is the use of 'has' appropriate with first person singular?

We have been learning since childhood that
'Has' can only be used with third person singular
but I have seen and heard people using Has otherwise, Like the other day I
was reading that article in which author wrote 'I has no other
choice'(which according to grammar rules should be 'I have no other
choice' )
Is this appropriate use?If yes
then does it indicate some kind of emphasis or Is it used to give weight
to sentence?
