@terdon But what do I know?
Chichurrito is some Tex-Mex or perhaps Mexican term unrecognized by the DRAE.
Chicharrón, in contrast, they do recognize as a word with various senses in (Latin) American Spanish, including pork rinds, adulterer, and somebody who got way too sunburnt. It’s related to
(a)chicharrar, to deep fry something till burnt. That said,
chichar is also a vulgar LatAm slang expression for
joder, follar.
