google search shows that out of eechuta, ichuta, & echuta, this is the consensus spelling. urban dictionary is the link (of the ones above) which will give origin, if not necessarily conclusive definition.
Disappointing that m-w doesn't seem to have it and google turns it up as mostly some kind of fantasy name. Google "sellion rhinoplasty" to get a closer definition. Roughly speaking, it's the most inset/indented part where the brow meets the top of the nose.
'But the most telling objection is "the suggestion (not explicitly articulated yet clearly implied) that the rules allowing the system to answer questions at native-speaker level can be couched merely in terms of manipulation of the symbols of the language", without requiring an understanding of "abstract patterns transcending the signs of Chinese, or of any human language - patterns behind the scenes, having to do with how ideas and concepts and knowledge are represented in complex, overlapping associative networks in the human mind".'
Searle is silly and wrong, but this is not such a strong objection. "Complex, overlapping associative networks" aren't some magical boundary of requiring comprehension vs. not requiring comprehension; they're just a massive & massively complicated set of contingent rules.
