Carcinojenny 

An otherwise attractive woman who ruins it all by smoking - a reference to the carcinogens contained in cigarettes.

"I thought that she was hot until I saw her light up and realized she was a carcinojenny."

"The best thing about a carcinojenny is that she is guaranteed to have an oral fixation."

"The entrance to the club was crowded with carcinojennies smoking in the cold."
