Meaning of がい in だろうがい


What exactly does "がい" mean in the phrase "リーダーは俺だろうがい"?

To give some context, here's part of the video I heard it from:

This was said by a comedian, so maybe it's an exaggerated and uncommon way of
speaking.

Or maybe it's just "tough guy speech."




「～～だろうが」 is an accusatory sentence-ender used primarily by male speakers. The
「が」 is a particle.

「がい」, though not too common, is an emphatic and tougher-sounding version of
that 「が」.

Likewise, for emphasis, 「か」 for questioning becomes 「かい」 and 「だ」 for
affirmation or declaration becomes 「だい」.

Though 「かい」 and 「だい」 are far more common than 「がい」, I do not think 「がい」 is
dialectal. (The speaker in the video grew up in Kanagawa, which is right next
to Tokyo.)
