Smallium
The unnecessary middle ground between small and medium in pizza sizes, created by Domino's Pizza when they decided to make the 555 Deal more expensive, and downgraded the mediums previously available to ten inchers for the so-called "444 Deal" in a foul effort to strong arm customers into shelling out the extra coin for proper pizza satisfaction.
Fuck Domino's. They can take their smallium pizzas and get back to post-apocalyptic London where they belong.
