percolegism
noun
Refusal to accept an incomplete collection.
Browsing her local comic shop, Annmarie was pleasantly surprised to find a figurine of Malcolm Reynolds from Firefly. She was about to buy it when she noticed Zoe and Wash on an adjacent shelf and realized it was a set. Getting excited, she scanned for the other characters - but there was no Jayne. Disappointed, she left without buying anything, knowing her percolegism would prevent her from being able to enjoy having some but not all of the crew of the Serenity.
