look up any word, like daquan:
A slang term used among many avid bird lovers or wildlife rehabilitation workers to define the particular defense display that is unique and limited only to barn owls. A barn owl, when cornered, will fan out it's wings and lower it's head, swinging it slowly from side to side as it hisses. This display is termed as crop dusting.
"wtf is that owl doing?"
"crop dusting, leave it alone."
