gunky

We looked for cloths with at least 100,000 fibers per square inch—the greater the density the better the grip on gunky stuff—and that can withstand at least 300 washes before going into the bin.

When force is applied, this gunky goo acts like a solid, and keeping it that way requires constant pressure.

Why do you think it was so prone to scratching and going all gunky after a year in your pocket?
