vaticidio 8
I was going to joke that it was the "murder of a poet", but I saw it written somewhere, so I think it is used. It would also be that of a prophet, because it comes from the Latin vates, is which is interpreted as "inspired by a divinity", which includes rhapsodes and fortune tellers. And although it seems that Sergio M originally had a similar idea, the truth is that bato is written with /b/, so those definitions -more than prejudiced- are not a joke (if someone says that baticide is the crime that the Joker dreams of, it may happen). See suffix -cidio ("to kill").
