i beg to digress - You start talking, but you’re confused and you say something

You start talking, but you’re confused and you say something stupid because you think you’re being fancy.

I beg to digress, I’m not confused, I’m just being fancy.

I beg to digress, I don’t know what that means, but it sounds cool.

I beg to digress, I’m not wrong, I’m just being fancy wrong.
