When a person does something so idiotic that you cannot even grasp the concept of how f'ed up it was.

Example:

When a Police Officer stops a vehicle and a subject runs from the vehicle into the woods. The said Police Officer stops another vehicle with a subject matching the exact same description who is sweating his ass off and breathing heavily. Put him in handcuffs, found green leaves in the floor board and seat of the vehicle matching leaves found in the same area the subject fled from. And the nephew told Officers the subject ran up to his residence found in the same area asking to use his car..... BUT LET THE GUY GO!!!!
What the hell was he thinking? I'm just.... BUMFUZZLED!
