First pets name+mothers maiden name. I tell ya, it sounds like a porn star,
My first pet was a budgie, and my mum is half Welsh.
Yours,
Bobby Powell.
Fluffy Smith at your service!
Fluffy was our cat, but when we got her spayed all her hair fell out. We then called her “Skin”.
The best pornstar name I’ve heard is my friend Pussy Budibent.
(I’m getting déjà vu - think I’ve posted this before sometime.)
Chico Hoover.
I’m not proud of it, but…
Uh oh, mine would be Moe Klein. I sound more like a doomed gangster from The Godfather!
(My real porn star name would be Rod Magnus, and Transformers fans will get the joke.)
Shelby McNally.
That’s no porn star, that’s a Civil War general.
Yankee Gabbard. Not very special.
Or you could use this to generate your porn star name.
Cockney Sin. That sounds better. Kinda.
Bandit Roberts.
Not to be confused with the Dread Pirate Roberts, mind you.
Sam Slate.
I’m ready for my close-up. 
According to the name generator, I’m “Hottie Sparks.”
Using the original formula, I’m “Colleen Waller” (first pet’s name + street you grew up on.)
Using SDMB formula, I’m “Colleen Torres.”
I read a celebrity version in Entertainment Weekly. Someone (don’t remember who) wrote “Fudgie Crown,” which was just ghastly.
Are we really bored today?
–Pretty Boy 130th
Oops, that was the original formula, 1st pet name + street where you were born. I guess according to the formula in the OP that would be
--Pretty Boy SmithPierce Canyon, at your service.
I’d be rocky maple .
hahahaha
“Buford Crum”
However, I’d prefer the name “Randy Johnson.”
Yikes, my first pet was called Halloween, Weenie for short. That being said, the options are:
Pet + mother’s maiden name: Weenie Wolf
Pet + street I grew up on: Weenie Pacific
From the name generator: Mary Ellen Black
Ciji Reid, according to the SDMB formula.
Ciji Michel Delving, according to the original formula.
Susi Mull
Mine is boring, so I’d go with Ben Dover.
