What is the meaning of pifflesnort?

I'd also love to know that. I'm trying to decode it but not sure if I got it right.
Is it a compound of : piffle + snort ?
Is the piffle here a verb or noun ?
piffle means nonsense or more informally rubbish;
It is usually : to talk piffle
Does the usage of the word snort downgrade the meaning from talk to mere noise ?

I hope that the attempt on explaining the word won't kill the joke.

I hope that the attempt on explaining the word won't kill the joke.

I fear that that is what is already happening. It wasn't exactly a "joke". It's simply the fact that the word "pifflesnort" was being used to denote "nonsense" and the word is itself "nonsense" (ie it's a non-word).
