When a character uses living ribbons (or ribbon-like appendages) to restrain themselves or another character.

This is NOT for characters being restrained by non-living ribbons (e.g. gift wrap ribbons), use ribbon_bondage instead.

See restrained for more about what counts as being "restrained".

Character ribbons also fall under the category of a prehensile_(disambiguation) structure. However, a specific category for ribbons does not exist.
