guttered or gutted

I discover that it is not uncommon for people to say I was guttered rather than I was gutted. This is an obvious mishearing of gutted, but it is puzzling in that I would have thought that gutted is not an unusual or difficult word, and guttered makes no sense.  I guess the image is of being left in the gutter!

 This citation from a novel by Meredith Moore (2016) makes the meaning of ‘being in the gutter’ almost believable:

“I was guttered last night, and I acted inappropriately.” I breathe out, relieved. So I won't be fired, then. “I take it 'guttered' means really drunk?” He almost smiles.

 The recent claim that the legislation on gun ownership would be guttered was arresting. The meaning is, figuratively speaking, evisceration, so the notion of the laws being dumped in the gutter was distractingly amusing.
