mr griffin who is this guy?

I keep seeing this in a lot of comments. I have no idea why this appears a lot. Is it a sort of inside joke in this sub?

Peetah, I need help

Petah

I know nothing about cars (I never got my license)

Peetah, what does this mean ?

I genuinely can't tell if this is an actually AI or not
