Patent Pending

On the way home from the airport, it occurred to me that My Robust Pregnant Wife had been in the car for over an hour and a half, and it had been raining all day, and her bladder is now the size of a styrofoam packing peanut, so I asked if she wanted to stop at Taco Bell and use the restroom.
"No, I'm fine."
"Would you like a taco?" Pregnant women are also hungry a lot. She frowned.
It occurred to me that she's a vegetarian. I added:
"A veggie taco?"
And then, inspiration:
"A veggico?" (Pronounced "ve-hi-co" as in Mehico.) A Mehico veggico. Let's-a-go!

Two english chaps in unflattering clothing clink glasses: "Brilliant!"
