Haha I like silly phrases, in Hairy Potter (book two) (yes, reading HP, I need shot) there is a house-elf called Dobby who beats himself up when he does stuff wrong: "Dobby must punish himself". Over time I translated that to "Dobby must kill himself" and then "Dobby must kill you" to make it sound evil... especially with the slow, twisted voice.
Again, did it on FL.
Lyrics
Dobby must kill you
Dobby must kill you
Dobby must kill you
Dobby must kill you
Dobby must kill you
Dobby must kill you
Dobby must kill you
Kill you
Kill you
Dobby must kill you
Dobby must kill you
Dobby must kill you
Kill you
Kill you
Kill... you...
