This phrase was a marketing catch-phrase for the Nexus-6 model android, as found in the movie Blade Runner and the short story on which it is based, Do Androids Dream of Electric Sheep? by Philip K. Dick.
The song by White Zombie is a direct reference to the movie, and in turn the short story. In particular, these lyrics are of interest:
I am the Nexus One
I want more life, fucker I ain't done (yeah)
This is interesting because, as we discover in the course of the story, the Nexus-6 androids which are being hunted are busy trying to find the man responsible for their manufacture because they are upset that they have been hardcoded with lifespan limitations. That is, after four years, they die. They are angry about this. They want more life. Despite their efforts, this is not possible.
Although no Nexus One model android was mentioned in either of the primary sources, one can presume that it may be an older model of android in the same line. And, of course, it rhymes.
Although most of the rest of the lyrics are fairly nonsensical, one can imagine they express the rage these androids felt.
