The word reminds me of fugacity, frequently encountered in chemistry/thermodynamics. It indicates the potential of one chemical substance to stay in one phase as a liquid/vapor/solid,

Fugacity: A community in which the dissociative disorder is prevalent. Nobody is quite sure who they were born, what it is they're supposed to do for a living, or whether they're with the same person whom they married or whose children are living with them
