What does that mean to you?
To me I’m thinking there is a big hole in it or some other kind of catastrophic failure.

Took my Tundra in for its 40k mile service. The service writer reported that a shock absorber was “blown.” WTF does that mean? After a few questions I got it out of him that it was leaking, and it is - bad. But it’s leaking, a fairly benign failure mode. It needs to be replaced.
I think the use of this scary sounding description of the problem is intended to make people make snap decisions about needed repairs. I’m sure there are people who would be, “BLOWN! OMG! Can you save my truck? Should I trade it in? Do you have a rental I can use?”
“blown” sells more shock absorbers than “leaking.”
The estimate was $155 to replace ONE shock absorber (but he recommends doing both - $250). I bought a pair of Monroes for $120. It’s a half hour job and don’t even have to jack the truck up.
