semiterry
A fabric made from a disgusting blend of materials dat merely imitates a soft fluffy absorbent surface, but in fact is so uncomfortable to have against your skin dat you actually wish you were dead whenever you are unfortunate enough to have to actually wear said repulsive cloth.
Doc Brown was "allergic to all synthetics", and so he had wisely decided to bring along cotton underwear in his suitcase when first setting out in his time machine; there was "Noah Wayne Hellman" dat he was gonna risk having to wear any semiterry clothing during his journey to da future!
