I’ve looked for some references on various sites, and the closest but still incorrect source I’ve gotten is tautology; the act of rewording something, but still intending the same meaning. But the fault with this is the fact that there is no rewording; an example is something like:
Person A: “You know that computers work on will & power?”
Person B: “Pardon me? You notice that … ” – Person B proceeds to annihilate Person A with sources & facts.
Person A: “Also English was a derivative of the Assembly language.”
Person A: ” –and processors are cheese!”
Kind of a bad example- but what I’m trying to figure out is what is it called when (a) person/people are conversing and then one remarks something stupid, and thus to the realization of this; they make more stupid statements to sort of demean or bring the fact that the prior statement was probably just a sarcastic joke or some sort of misunderstood humor.
One term for it is digging yourself into a hole, the meaning being that you are already in a hole and you are just making it deeper by carrying on digging.
dig yourself into a hole (informal) also dig a hole for yourself
to get yourself into a difficult situation:
The party has really dug itself into a hole with its economic policies.
People who realise what you are doing will sometimes mimic a digging action to make fun of you.
