hang by the eyelids

hang by the eyelids

To have a loose grip on something. Can be used either literally or figuratively. For the tug-of-war, don't just hang by the eyelids, gentlemen! Really get a secure grip on the rope and keep a strong stance! I currently have a D in this class, but I'm just hanging by the eyelids—I really need to get a tutor.See also: by, eyelid, hang
