surname, attested from late 12c., probably meaning bald head; cf. Wyclif Stye up, ballard, where Coverdale translates Come vp here thou balde heade [2 Kg.2:23-24, where God kills 42 children for making fun of Elijah's lack of hair.]
A slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or rock layers moves a short distance down a slope. Movement is characterized by sliding along a concave-upward or planar surface. Comments.
But severe afternoon slump should not be dismissed as an ordinary and expected part of your work day. Extreme fatigue, especially when the symptoms of shakiness, dizziness, or sweating are present, could be a warning sign of reactive hypoglycemia. Severe slump symptoms include a profound and intense desire to sleep, muscle fatigue, sweating, the shakes, headaches, changes in vision, or any combination of these symptoms.
