1.
Fundamentalist Christian. Religious to the point of crazy. Bible bashing, racist, sexist, homophobic, self righteous nut jobs that believe in the literal truth of the bible. Described by George M. Marsden as "militantly anti-modernist Protestant evangelicalism."

2.
Used to describe a woman that is "so-so".

Guy A: She's no profundo. I mean, she's not that hot, but I'd still give her the time.
Guy B: Yeah, I'd- I'd give her the time.
Both: Nod.
Both: Fundo. (Both then assume the Fundo position)
