A reference to young men who grow scruffy beards, wear their hair in a greasy and disheveled fashion and wear surplus military field jackets in an apparent attempt at duplicating the stereotypical media image of a traumatized war veteran.
That young twenty-something with the darting eyes and the spastic movements whom I saw sitting in front of the English department seems to be affecting quite an elaborate shell sham.

Men who ride Harley's or other cruising type bikes, who wear turtle shell style helmets because they are not driving fast enough to need a full helmet usually. And they ride on a bike that has had custom steering handles installed. The handle bars are usually raised an additional 10 to 12 inches, making the rider appear to be hanging from a monkey bar.
"How bout that turtle shell on a monkey bar, his tiny helmet had huge skulls painted on it and he was barely able to hang onto his monkey bar because it was almost too high..."

The act of aiming only to wreck/spinning out the first place person in a racing video game; much like the spiked shell from Mario Kart. Often frowned upon and seen as immature.
John: Me and Mike spent all last night spiked shelling in Grid. We almost took out the whole field, one by one.
Greg: You're a douche. Grow up.
