Among my Spanish speaking co-workers (\*12 hour shifts - metal plating production - we all work hard) they call me "Wedo" because I'm the only white person on my line that can uphold myself 6 days a week at the same pace as my Hispanic/Latin peers.

It's used as a term of endearment in my situation - but basically can mean a blonde non-white or fair skinned person of Hispanic/Latin decent. Or just white as others have stated. It really depends on the inflection of how one may be referred to when the word is used.

I love it because in my world it means I'm on the side of my peers, not some stale square saltine good ol' boy.

The way it was explained to me was that in this instance it carries the same connotation as "red" or "yellow" bone does in African American culture. If that helps as a reference.
