Obtruder

undefined:

An obtruder is a headmate that intentionally mocks, sarcastically encourages, and/or guilts other headmates for their intrusive thoughts. This is done with the intent of wanting other headmates to feel ashamed for thinking this way (out of a belief that the intrusive thoughts are the secret wants of the headmate having them). Obtruders may be scared of the thoughts becoming reality, and simply try to prevent this from happening using harmful methods.

Due to the nature of this term, it should only be used for self-identification purposes.
