shell sham

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.

shell

v. to tuck your bent legs against your chest and pull your shirt or sweatshirt down over your knees, usually in an attempt to make yourself feel warmer

The wind this morning made me so cold that I had to interrupt my walk of shame and sit down in the middle of campus to shell for a couple of minutes. I knew it was a stupid decision to wear shorts out last night!

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.
