Top Definition
A common occurrence of hazing perpetuated by US Marines assigned to helicopter squadrons against one and other. A Marine is tackled to the ground while other Marines jump on top forming a stack. Usually the largest Marine is the last one to jump on top high above from a table of other platform. Occurrences of stacking are much more common on deployment but sometimes stacking wars can erupt between shops at home. Flight Line is by far the most notorious stacking shop. A smart Marine from another shop will always check the ground for any taped silhouettes of human figures as stepping on one of these will get you stacked in a heart beat.
