1. A male homeowner who thinks he knows how to fix anything, so he refuses to hire anyone to make any repairs, thereby totally screwing things up much worse.
2. Same as #1, except he goes ahead and hires someone, yet tells the repairman how to do his job.
I'm an electrician, and I had a real Tim Taylor for a customer today. He stood around and told me how to do my job his way, and wouldn't let me do my own work properly.
