Cry from Homer (3)
I believe the answer is:
doh
'cry from homer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for doh that I've seen before include "Note; exclamation" , "First note of tonic sol-fa scale" , "whoops!" , "The note C" , "acknowledgment of stupidity" .)
