Canthal tilt
The canthal tilt is the angle of the lateral canthus (outside corner of eye) in relation to the medial canthus (inside corner of eye). A positive canthal tilt means the lateral canthus is higher on the face in proportion to the medial canthus, whereas a negative canthal tilt means the lateral canthus is lower on the face than the medial canthus. A negative canthal tilt is an extremely unattractive feature on men, as it looks droopy and unintimidating.
