According to The Simpsons the name 'Homer' became a noun roughly meaning 'a clumsy and often stupid mistake leading to a fortuitously positive outcome'. I think it was due to him reacting completely foolishly during a reactor overload, but somehow, managing so to avoid a catastrophe. As an example in that episode they had Dennis Rodman fall over while trying to complete a play landing in a group of friendly cheerleaders and proclaiming, 'Oh, I did a Homer'!
