From Spanish to English
Immediately coming to my mind is the Spanish (Mexican, really) word "ningunear".
In English, this verb means something like
"to render someone into a no one"
The noun form "ninguneo" means something like "a no-bodying of someone"
Approximate terms in English like "to snub" or "to ignore" are nowhere near as strong in their implications.
