cribbing
n.— «A stable vice is an undesirable behavior demonstrated by horses that are stall bound but also in pastures or small paddocks. The most common stable vice is probably “wind sucking,” commonly known as “cribbing,” followed by wood chewing, stall weaving or walking, and fence line pacing. The stable vices are classified as “compulsive” behaviors and termed by some as true addictions.» —“Book Excerpt: Stable Vices” by Michael Ball TheHorse.com (Lexington, Kentucky) May, 2006.
