A human being who is so inept that their intelligence is below that of not just a donkey, but a donkey with special needs.

Can be shortened to "SND".
"Did you hear that question Special Needs Donkey just asked me? How does he even dress himself in the morning?"

"My boss is such an SND; I can't believe he got me to help him dial the phone."
