Our reading
An editorial interpretation.
The speaker describes discomfort as an overwhelming feeling of ickiness, using an informal word rather than a precise explanation. That contrast gives the statement a blunt, conversational quality. It communicates the strength of the aversion while concentrating on the unpleasant feeling itself, rather than making a detailed accusation.
