“Aslan is on the move.” Obviously.

Hey, that is as geeky as my joke and from a very similar source.
Mine would be…
blinkingduck.
I don’t know what I would want my code name to be but I am sure they would end up calling me Orca or something like that.
I think I’d be flannel.
Maverick or Iceman. 
It wasn’t President Clinton’s official code name, but the Secret Service agents from the security detail whith whom I had the opportunity to work referred to him among themselves as “Charlie Foxtrot,” which is radiospeak for “CF” which is generally short for Cluster F_ck. Gives one a pretty good idea what they thought of the guy.
A friend of mine but especially my wife is the son of a high ranking Secret Service agent with a career in presidential detail. Unlike most other people growing up in similar circumstances he does not lie or brag about his father’s job or what he got to witness first and second hand. In fact, he claims that it destroyed his life (which it looks like it did) and made him so cynical of the government that he claims he is an anarchist at this point. He doesn’t talk about it much but I have gotten the nerve to bring it up a time or two each year.
He can give a detailed summary of what problems each president and their families caused the Secret Service starting with Gerald Ford. Ford was easily the best according to him and Reagan wasn’t far behind. The Clinton’s were the worst. Bill Clinton did what they suggested in critical situations but obviously put them in very awkward situations by smuggling certain people into the Oval Office and forcing them to protect the entrance as well as violate protocol by making them allow certain people in with no security restrictions. The Secret Service didn’t just have to comply but also keep it completely secret while they tried to hide their disgust of the whole thing.
Hillary was supposedly much worse. She didn’t smuggle interns in but she questioned their plans all the time and forced them to change them at the last minute to serve her whims. Presidential protection plans require a lot of work and preparation but she didn’t seem to care about that even in terms of her own safety.
Hedgehog.
Alpha Bitch
and don’t talk to me about profanity, every dog has a mother, are you disrespecting motherhood?
If that argument doesn’t work, I’ll insist on Whisky-Tango-Foxtrot.
That’ll get me Alpha Bitch. Or at least Whiskey (with the ‘E’).
Wildcat. Or maybe PMS.
I’ve got it! “Ron Jeremy.” Someone mentioned “Hedgehog” above, and that made me think of it.
Delorean.
Props to my husband for that one. I came up with Nurseshark for myself (I love sharks and am a student nurse), but Delorean is much classier!
I read an article once which was supposedly the candid opinions of a Secret Service agent who had guarded both the Clintons and the Bushes. It more-or-less matched up with what your friend says. Basically, Hillary treated the Secret Service guys like dirt, and they all hated her. Bill was much more polite and amiable, but his extracurricular activities caused no end of grief for his security detail. They liked George and Laura Bush a lot better. Especially Laura.
As for me, it would probably be something I’d hate, like Tubby.
Long Dong Silver
or
Love Machine
Shaft.
The drunkard.
Yeah, there’s no way the Secret Service would ever be guarding me…
Eagle is down
I’d use my RL nickname: “Oswald”
I find it particularly hilarious the Secret Service would have to protect a man that takes his nickname from a presidential assassin.
Tripler
Yup. Definitely “Oswald”.
Guys I work with like to call me Darkshine.
Though the secret service would probably just refer to me as the designated target.
