Grampster 

A man or woman aged 65 years or older who considers them-self to be a gangster. They are usually thugged out with ghetto wear, and have tattoos all over their bodies.

Did you see that 70 year old Grampster with the flat billed Twins hat? I bet that old bastard is hard as hell and is packin' serious heat.

Guy 1: You better watch out for that Grampster, he won't hesitate to bust a fat cap in your ass.

Guy 2: Yeah but he'll probably break a hip trying to catch me!

I bet sawdust and mothballs would fly out of his pockets if that old ass Grampster fell over!
