The Grinder- First discovered on a Doom 3 demo, is the god of all grinding machines. It is basically a cylindrical pit with a catwalk just overtop of it. Only half of the pit is visible, as the other half is covered (it is a rather shallow pit). This cylindrical hole in the floor has two rotating arms of great mass that rotate at sonic velocities from the center, sort of like a misshapen giant food processor. Countless monsters can be spawned in the grinder only to see the arm sweep them underneath the covered section, and the same arm emerging with nothing but a bloodstain.

The grinder, after being discovered, became the primary method of producing Noobioes, The Breakfast Of Champions. The process is simple- all the noobs of the world are captured in their gaming sessions and MS-DOS prompt "hacking" sessions and are thrown simultaneously. When the grinder is turned on, all the noobs become something like ground beef, and they are then removed and turned into little 'O' shaped cereals. The grinder is truly an amazing device that is not to be taken lightly - however, if wrenches or chairs are mistakenly thrown into the grinder, jamming and lag are sure to ensue- so be careful on the types of noobs that are thrown into the grinder.
"I heard Gerald got turned into noobioes"
"How did that happen"
"Simple, he was thrown into the grinder on the Doom 3 demo."
"Well, he has been turned into something useful! The breakfast of champions!"

Girl you know I'm a grinder
I can't let you hold me back
You want too much control
It's bringing me down
I have to stay in the grind
And make money and do good things for me.

A tough, unspectacular hockey player who is willing to do whatever it takes to get the job done. This is usually meant to be a compliment; a "grinder" is usually an overachiever.

Tough, gritty, hustling hockey player who stops the other team from scoring rather than scoring himself.

-Can you get me a turkey grinder, Jethrow?
-What is a grinder, sir?
-Sorry Jethrow, I forgot that you're an illiterate southener. A grinder is the same as a sub, a hoagie, or a hero.
-I understand now. I'll make you a grinder now. Thank you kindly.
