Mars Volta - Vermicide

What does 'Vermicide' means? It's actually a worm-killing medicine. I pretty unsure what the word actually means in this whole song.

This song has a powerful guitar rifts and effects (you, guitars pros - help me on this!)plus multiple voice reverts if you listen carefully to the studio version. In this live performance at Troubadour, L.A., I can say it has no differences than the studio version, but the Mars Volta has omitted some lines from the enraging chorus - of course, plus the vocals impact by high-pitched lead vocalist - Cedric Bixler-Zavala.

Anyways, it still sounds great as ever. Such a powerful chorus - "Mark the!" "Venom!" has put the fans gone wild!
