personality excrement

A supernatural fetish in which a victim's personality/soul is transferred to something inanimate and excreted out, leaving their body an empty shell.
Defecation (as a brightly colored jelly) is the most common medium, but cum, lactation, vomit are also possibilities.
If personality is not a factor (for example, when injecting colored jelly with a large syringe), please use a different term.
