chipping
 n.— «He was called on constantly to help out overmatched right tackle Grant Williams on pass protection, and when he did, Jackson slammed his 6-foot-2, 231-pound body into 49er pass rushers like a bone-jarring battering ram. In NFL parlance, they call that “chipping.” But to see Jackson do it with such a thunderous zeal, the term “chipping” is insufficient. “Sledgehammer” seems to create a much better mental picture.» —“Student makes his teacher proud with an outstanding performance” by Bryan Burwell St. Louis Post-Dispatch Dec. 5, 2004.
