olfactory "hallucinations"
When you smell something that really isn't there.
I've had many olfactory "hallucinations" like when I smell mustard & there's none around!
encopretic olfactory hallucinations
A description of the neuropsychological disorder wherein a person erroneously believes they have shit themselves.
Sadly, during his early childhood while visiting his dad in prison, Jared was dropped squarely on his head and ever since this unfortunate event he’s been having these disruptive encopretic olfactory hallucinations which has caused him to wear the now familiar “Kushner shit smelling face.”
