From Oxford Dictionary where knowledge is a cool thing, the big reveal:
Onolatry
Worship of the donkey or ass, onolatry has also come to refer in extended use to “excessive admiration for or devotion to foolishness or a foolish thing.”
Thank you Oxford Dictionary.
(And speaking about an ass…Happy Anniversary honey! Yes, you forgot again)
