Grizzle (v) The act of being Grizzled. Derived from the manner of a Grizzly bear. To be beaten half to death, scalped, licked upon the forehead, and to be shit on. Based on a true Grizzly Bear encounter. Hence, to be "Grizzled."
Any dirt or grease left behind after someone uses the phone or a combination of the both. Appears to look like crisco with small black dots of dirt. Otherwise known as phone smagma.
Oh man, make sure and wipe off the phone because Dale just used it and it is full of grizzle.
