Smoge

Smoge: noun. The smoke created by a smogie. This word was first used in Dublin in 1907, when the concentration of smoge in the city was so high that it forced the majority of the population of the city to flee into the countryside, as well as killing over a million cats, rats and possums. Thanks to a strong-eco-friendly effort on part of James Joyce the city was cleaned and world-wide levels of smoge have since then remained low thanks to a worldwide increase in cigarette quality.
