Cornish Gay Men

Much like Cornish Game Hens the Cornish Gay Men can be recognized by their puffed up chests.

The term is used to describe any homosexual male that over works their chest and shoulder muscles in the gym resulting in puffed up chest with slender "toothpick" legs to support his body.

Going to Gay Days was so obnoxious, everywhere you looked there were Cornish gay men, I'm amazed their legs could support their chest!

Cornish Rex 

A feline-like costume worn by small aliens as a disguise while they study Earthlings.

“Dude! Why does your cat look so weird?!”

“She isn’t a cat! Gweny just wears her Cornish Rex costume because it makes her look like she ALMOST belongs on this planet.”
