Amanda - Head Bitch on Duty.

Multitaskers
BaseballMom - I guess if I had a business card, it would list, 'Tyler & Alex's mom, Raptors team mom,. Crossing guard, Lunchroom lady, and School volunteer, as well as PTA pres., laundry lady, cleaning lady, camping fan, and reader of good fiction.'
Mary, mom to many - My hubby teases me about bursting into song at goofy times, so my card might say-- Owlhaven: Canary, Kid-Cuddler, and Story-Teller Extraordinaire

They have official badges and everything.
Ben - Shit-catcher.
Erin-erin-bo-berin - Crime Scene Investigator :"Who gave that to you?" "Where did it come from?" "How long has that been under the sofa/in the car/under your bed?" "What's that fuzz all over it?"

Danielle - AKA "I'll be there in a minute".

It's all about the perception. And the outfit.
Marla Good - Marla Good, Imperatrix. It’s not the best word by definition. It’s just that it sounds like a title that would come with a... let’s say...rather kicky uniform. And it definitely implies that I rule. Or, if I were feeling slightly less smug, I’d settle for Marla “Very” Good."

I hear her war room is stocked with liquor and munchies.

Mamacita - Professor: School of Hard Knocks and Grammar. I learned it all the hard way so you won't have to.

Once upon a time...
Jerri Ann Reason - My family calls me the story teller. As you can see by the two questions I answered in depth, everything has its own story. So, some kind of title involving that...maybe The Family Historian or just plain Story Teller

It's an art.
Donna Schwartz Mills - Whine Enthusiast. Kvetching about since 1956.

I've got one already... check me out:
Margalit - OOO, I know this one because I DO have a creative title on my business card! My job title is Thought Leader, CNO. CNO stands for Chief Nudging Officer. Really, this IS my job title!
Chris - Slave to the lilliputians.

Bon Vivant
Deana - Master Illusionist
Rbelle - R*Belle the fabulous!
