An imaginary monkey on your back who messes things up for you. That monkey is your dobro. It is associated with social and physical blunders. Can be used as a noun, adjective or verb.
It is important that whatever the dobro messes up or "dobros" for you must have had a legitimate chance of success. Outright failures and belligerent actions are not dobros, or are not caused by the dobro.
