Answer:
The word "corvus" means raven or crow. The Romans taught the ravens to talk, as in the story where Augustus bought a raven whose owner had taught it to say "Hail, Augustus, the victor". However in popular slang it had a more sinister connotation pertaining to crucifixion. The term "in cruce corvos pascere" meant to be crucified, or "corrorum cibaria" which meant food for the crows.
