These are lyrics of a rock song. "You wanna make her" is a crude way of saying "you want to make love to her" or "you want to have sex with her". A "suicide blonde" is term that refers to a blonde-haired woman, often with really extreme makeup, who is very glamorous. You could say she is "to die for" in order to exaggerate how pretty she is, but it is not literal. So altogether, the sentence means "do you want to make (love to) her? (to that beautiful woman)" Here is the wikipedia page about that title track of the INXS album: http://en.wikipedia.org/wiki/Suicide_Blonde

you want her to kill herself.
