an irrational and irritable assclownish beast that is completely immunized {hannitized magatized} to logic-or-reason, any-and-all negative facts-or-evidence concerning Trump, and remains a devout and mindless supporter of the buffoon.
An irrational creature prone to wild overreaction, rattling its cage at the slightest provocation and indiscriminately flinging its faeces around until everything is covered in excrement.
(That is the original definition from the person who coined the term)
