COG 

COG: A cat that behaves like a dog. A dog in a cat's body.

Simba the cat is real COG. He fetches like a dog and chews on shoes like a dog.

COG 

Creepy Old Guy. An older guy that prey on younger girls in clubs. Normally he stare intensely at the girl’s private parts and licks his tongue.

Not to be confused with the Silver Fox, an older gentleman like George Clooney.

A COG is tacky and freaks out people.

That guy stare at me is such a COG.
He is COGING her like crazy.

Cog 

A cat that is so dog-like and affectionate it betrays the stereotypically stoic nature of the feline.

My cat is a total cog -- he can't fall asleep unless we're spooning.
