grotesque
groh-TESK/ɡrəʊˈtesk/
Strangely distorted or absurd in appearance or character.

Etymology
The cave reference plausibly comes from fanciful paintings found in excavated Roman ruins. A term for fantastic decoration later became a negative description of what looks distorted or absurd.
In context
