I am both Mr. Largepizza and Bridgette in this scenario depending on what day of the week it is.
I had concerns about even doing this storyline, but I'm enjoying the heck out of it thanks to this "the characters are acting" nonsense.
I might have gotten a little lazy with the "Mr. Largepizza" name, but I assume any name that is a combination of toppings is almost certainly already an obscure mascot for some pizza place somewhere.
As for Bridgett for Ashley, I would like to claim it's for some clever reason like "Ashley starts with an A, so let's go with a B name!" But no, it's the first thing that popped into my head, and I was like "cool, let's go with that."
People have speculated about what "pizza" is a metaphor in this storyline, but really, it could be pretty much anything people have opinions about (up to and including pizza) with the cohesiveness of the metaphor fluctuating depending on what you replace pizza with and the particular moment we're at.
