The English word rabies is said to derive from the Sanskrit term rabbas meaning to do violence.

Here’s a short excerpt from Palahniuk’s fine book:

As I understand it, you have two types of rabies. There’s your “dumb” type, where you never go insane and bite anyone. You only curl up in a ball under your bed and die. And there’s the normal kind of rabies, the “furious” type, which 80 percent of folks get. Where you slobber and swear and flail around, smashing everything in your bed-room including your Dolls of the World collection, and calling your father a “dirty, shit-eating, motherfucking, dick-less dickhead…” Well, that’s what kind of rabies our Margot had.
