What does it mean when oil spews out of the exhaust pipe?

Serious trouble. It usually means a broken oil (piston) ring. Another possibility is that your exhaust valve seals are bad/gone or valve guide is worn in excess. Another possibility is it is condensation coming out of exhaust mixed with black residue from exhaust and only looks like oil.
