curl; tendency to curl
Refers to the curl or curling tendency in a rolled item like a poster, scroll, or cable, often from being stored rolled up.
The poster has developed a curl.
To fix the curl, it's good to roll it in the opposite direction.
Compound of 巻き (maki, 'rolling') + 癖 (kuse, 'habit, tendency'). The exact historical derivation is straightforward; the word describes a tendency to curl as if it were a habit of the rolled object.
