Demianro-Jump can be described as when one is normally demiromantic, but occasionally experiences rare, sudden, and intense spikes of anromantic feelings, or romance-repulsed feelings, before returning, just as suddenly, to one's normal amounts of romantic attraction.
Demianro-jump can be a romantic orientation on its own or can combined with other orientations. For example, one could be demianro-jump and omniromantic, meaning that when one is experiencing romantic attraction it's towards people of all genders.
The sexual counterpart to is demiance-jump. Being both demiance-jump and demianro-jump makes someone demianroance-jump.
