rapid unscheduled dis-assembly

That's the new way to say .....
' It done blowed up
'

That would work...
I've also heard "it's gone atmospheric", and "it let the smoke out".
I'm sure more will be added soon.

Sorry for your misfortune; BTDT, and only humor & sarcasm let me keep some perspective...

I heard it was the piston/rod delete button....

I'm not sure that was OP's misfortune, but it definitely was Elongated Muskrat's rocket that had to be self-destructed after boosters failed and it went off course, losing altitude. That is the term they used

Ventilated or windowed

I heard that the other day when Musk's rocket blew up.
