Movie Code Names vs. Real Code Names

I've developed the following theory using several minutes of careful thought. This is purely for entertainment, as I am not a real operative of anything for anyone.

In movies, and other works of dramatic fiction, characters often have code names related to their job description or some personal trait, either directly or in an ironic sense. Here's a list of some examples:

Chopper, Killer, Psycho, Vegas, Tex, Hollywood, Ringo, Doc, Cowboy, Hot Shot, Fireball, Iceman, Ox, Moose, Tiny, Slim (these two are reserved for the fat guys), Hawk, Snake-Eyes, 8-Ball, Joker, Ace, Lucky, Spark Plug, etc.

This is both cliche and stupid. If your code name tells your enemy who you are better than your real name, it's not a very good code name, right?

I have developed a better system for devising code names. A code name should be short; two syllables is ideal so it's mnemonic to members of your operation. It should be a word that is as nondescript as possible, something you could work into a conversation, and no one overhearing it would be the wiser. It should also be completely apropos of nothing with regard to the person. Here's a list of examples:

Soap Dish, Card Stock, Wood Chip, Fish Bowl, Car Port, Dial Tone, Man Hole, Side Door, Key Ring, Tin Can, Tube Sock, Tea Cup, Back Tire, Bike Shop, Note Pad, Wheel Well, Door Knob, Wrist Watch, Pin Stripe, Felt Tip, Floor Mat, Dust Mop, Ball Point, Phone Book, Shoe Store, Hair Brush, Sand Box,

For example, the code name Soap Dish. The operative you give that name to can't have a OCD hand-washing thing. He also can't be slippery or evasive, like a saboteur or con-artist, nor a guy specializing in marine operations, nor a money launderer. He also can't be ironically grimy or messy. You'd could give the code name Soap Dish to a guard captian, or a driver, or a demo-man, or a computer guy, or something like that. Your saboteur with the OCD hand-washing thing can be Hair Brush, as long as he has normal guy hair--no excessive product or frosted tips, nor can he be bald.

Give the stupid movie code name to the guy you don't trust. When he gets caught and sings, he'll throw your opponents off the trail.

Side Door Out.
