ultrafarts 

The most rank and resonant, and therefore the most elite, of farts.

He is the absolute, hands-down king of ultrafarts.

ultracrepidarian 

One who speaks above his level of knowledge, experience or expertise. From Latin Ultra=above & beyond + crepis-idis=sole,keel.

The story goes that when the famous Greek painter Apellis made a full-body painting of Alexander the Great and showed it to the audience, a shoemaker approached him and made some comments about the rendering of the sandals of the great warrior. The painter promptly acknowledged the error and with a stroke of his brush corrected it. But after a while the same man started to comment about the robe of Alexander and the painter cut him short by saying, "Stick to the sandals, my valuable friend".

ultratard 

An annoying person who thinks they are an intellectual genius, but in reality are extremely unintelligent. An ultratard will always jump into the middle of conversations and spout out useless and incorrect information. They will speak loudly when talking to one person so bystanders will be sure to hear their idiotic ramblings.

I asked him a question and he gave me a 10 minute answer that made absolutely no sense. He is a real ultratard.

ultracrepidate 

To criticize beyond sphere of one’s knowledge.

In a Roman story, a cobbler criticised the sandals in a painting by the painter Apelles, and then complained about further parts of the work, to which Apelles is said to have replied, "Ne sutor ultra crepidam", or, roughly, "The cobbler must not go beyond the sandal". As true today as it was then.

Yeah... an ultracrepidate alright...
