Old person, usually of grandfather age defined by an ability to nap through nearly any life situation. The term was given to describe the iron grasp such a 'grain grippa' has to their wooden rocking chair during such siesta.
Hit 'em over the head with a beer can or turn up the hit list as loud as you want, that grain grippa ain't gonna wake up for nobody.

Kick in his door, steal his wallet or crank up the hit list, that grain grippa ain't gonna wake up for nobody.
