How can an engine be blown?

Question:
What do people mean when they say an engine is blown? I assume they are saying the engine is no good and needs to be replaced. But any problems an engine may have can be fixed by replacing the broken/worn parts so how can an engine actually be blown?

Answers:

Having problems starting car. What is wrong?

Generally a blown engine means there was a catastrophic failure of internal parts that sends a rod through the side of the block or oil pan. Seldom are blocks salvageable when this happens.

it usually means no good, can mean blown head gasket-fixible, blown rod-maybe, blown piston-maybe, blown a hole in the block-not usually :(
