Insufferable Oaf
An 'insufferable oaf' is a term used to describe someone when they are deliberately being quite obnoxious. Most famously used by James May on Top Gear when they were all participating in a race along the arctic to the North Pole, and himself and Jeremy were paired together. James sat on the toilet seat on the rear exterior of the Toyota Hilux when Jeremy slowly pulled away, resulting in an angry outburst from James.
'CLARKSON!' yelled James. 'I know it's you you Insufferable Oaf, I'm on the bloody throne!' he shouted, frustratedly.
