"the other man" in spanish slang... you know.. that guy your girlfriend is cheating on you with...hey, I know this... this is my last name!
"I don't practice santeria
I aint got no crystal ball.
I had a million dollars but i'd,
I'd spend it all.
If i could find that heina and that "sancho" that she's found,
Well i'd pop a cap in "sancho" and i'd slap her down." - Sublime from "Santeria"

I agree with all of the above definitions (which are basically the same), but thought it was interesting to note that instead of saying "salut" when someone sneezes, most of the guys I know say "sancho" instead, which I guess means that if you sneeze that means sancho is at your house with your lady.
"achoo!"
"sancho!"

or, it i were to sneeze (being a girl):
"achoo!"
"sancha!"
