oblique — as in: an oblique reference
I sat up: oblique
strain to the cartilage between the lower ribs.
Patrick Rothfuss -- The Name of the Wind

Less commonly, oblique
can mean slanting in various senses, such as:
- An oblique line is not parallel or perpendicular to its reference line.
- An oblique angle is not a right angle or a multiple of a right angle.
- An oblique muscle is one that runs at a slant relative to the long axis of the body or relevant limb—such as the abdominal obliques.
