look up any word, like blumpkin:
 
1.
Heterosaurus — n
any large carnivorous bipedal dinosaur of the genus Heterosaurus, common in the UK in upper Jurassic and Cretaceous times, although recent sightings have been reported in and around the Teddington area. Remarkable for its overwhelming heterosexual demeanor.

Behavioural characteristics include wise cracking, tea making, moaning (usually about exertion or effort directed to produce or accomplish something), operating light weight machinery, sticking to his guns, wise cracking, encouraging tea making, laughing at his own jokes, dropping the c-word on anyone he thinks deserves it, voicing his dissent to a pedantic degree, questioning authority, wise cracking and displaying a bona fide heterosexual attitude.

Physical characteristics - think Pro Golfer Paul Casey...ish.

C19: from New Latin, from Greek heterannos 'straight as an arrow' + sauros lizard
Bill is a good old-fashioned heterosaurus.
