Pheasant-faced Guinea fowl 

A “Pheasant-faced Guinea fowl!” is an insult that is thrown about in disgust towards people that are stupid or uneducated. This phrase is usually met with the response of “hogwash you buccaneer!”.

Jenkins and friend:

“Tither, Thither, Jenkins! I do believe that man is quite the pheasant-faced Guinea fowl I believed him to be!”
“Quite right ol’ matey look at him strouthing around like a lesser-man”
Pheasant-faced Guinea fowl:
“Hogwash you buccaneer! Prepare yourselves for a dashing round of fisticuffs!”
