He was peeved that he didn't get any of the Big Tobacco Shakedown stimulus and the low tar and nicotine brands are not curbing his three pack a day habit.
The back story is, the red necks had been hunting earlier in the day and had liberally "juiced" their boots and hunting jackets, still in the back seat of the truck, with doe pee. Assuming that the desire of his olfactory senses was in the truck and the humans appeared to be in the process of getting between the buck and the object of his affection, there was nothing left for the Mother Nature bound creature to do but attack. Eating the cigarettes was a gesture of rebellion and contempt as the human, after the first good Btch-slap, refused to stand and fight like a cloven hoofed beast. Left with a raging case of the "Gotta Have Her" and the LEO's bearing down like a small army with Tazers there was little left to do but kick some butt, increase the body count, and take names of the injured. It wasn't a fair fight, 6 against one, but the buck met the challenge and emerged victorious scoring 73 to 72 on two of three of the Judges score cards for a Split Decision win.
