from Greek macro: something that is large or long and Latin vernacular: household, domestic, native.
Adj. a person, usually of the female variety, who talks obsessive amounts; to constantly chatter; to over use large or complex words often.
We used to call her a chattering vagina; however, it was rude, so now we just refer to it as her macronacular.
