Unsay used in a sentence

Unsay in a sentence as a verb

You can't unsay something you already said, man.

But even more important is the obvious - you can't just unsay what you said.

Practically tho, just as you can not unsay something said, nor put the dropped tumbler back together in the same way, you can’t rewind thermodynamics and you can never remove information once you have unleashed it online.
