A sick sexual urge for a hunter of large animals to fantasize as well as act out these fantasies of sexual intercourse upon their prey. This is typified by stickers on the back of their truck window displaying an animal and a double entendre worded below that could be taken as "hunter slang" but is really "animal sex code" for the initiated.
Hey Wilbur, did you see that Elk I tagged last night? I took my "Best Shot" and showed that "Bad Boy" who was boss, and it was a "Full Load". Next week when the bow hunt starts, I'm gonna "Give him the Shaft!". Just don't tell anyone that this is code for bestial eroticism...... shhhhhhhh.
