An act perpetrated by deer, most commonly Odocoileus virginianus, whereby an unsuspecting driver is tricked into pulling his or her vehicle to the side of the road whereupon he or she will be assault by the deer and its previously well-hidden friends. Most frequently the assualt includes, but is not limited to, butting, violent rubbing, pushing, shoving, spitting and musking. Humon victims are almost always shaken, but seldom injured.
Reports of attempted surprise buttsecks are not unheard of.
Did you guys hear what happened to that poor driver in Wisconsin? He was the victim of a deerjacking! Fortunately he got away with his rectum intact.
