grogbeard 

Someone who is both a grognard and a neckbeard. These are among the lowest of the nerds on the scrotum-pole of nerdology.

Two nerds are playing Warhammer 40k.

Grogbeard: You only get a 3+ armor save if you're wearing Astartes Power Armor. Quit cheating or I'm going to tell the judge on you.
Ordinary Nerd: Dude, quit being such a grogbeard.

Graybeard 

A middle-aged man. Old enough to have some white (gray) hair, but not completely white yet. Graybeards tend to think of themselves as wise and experienced, while younger people just consider them "old."

Dude, I thought that graybeard would be humming Frank Sinatra, but when I walked by his office, he was jamming to Brother Ali!
