I can't even pronounce nothing, pass that ver-say-see
“Ver-say-see” is a mispronounciation of the luxury brand Versace (pronounced vair-sah-chay). He’s making fun of the sort of person (himself) who wants to buy luxury items that they can’t pronounce.
Kanye seems to be imitating a line from Joe Ezterhas' craptastic movie Showgirls, where main character Nomi says “Thanks. It’s a Ver-sayce” after being complemented on her dress.
This also goes back to the previous verse where he added the “urr” sound to several words, poking fun at the parents of the girl he’s talking about.
