Not an engineer but my understanding is that it's an engine wherein a
loss of timing between the crankshaft and valve train (such as would
occur if a timing belt slipped or broke) would result in Mr Piston
getting to meet Mr Valve with typically diastrous and expensive results.

I think some engines (my old Fiat was one) could also have interference
between the crankshaft and the fuel pump lobe under those same
circumstances.
