A Fog Job is when a female is giving a male head, and the girl giving head is smoking a cigar or pipe at the time. The girl draws smoke into her mouth, goes down, and when the penis is as far into the mouth as possible, exhales the smoke, causing a foggy effect around the genitals.
A fog job is NOT a fog job when smoking cigarettes or weed.
Smoking weed and doing this results in a Joint Job
Hey I didn't like that Sarah smoked cigars, until she gave me a fog job last night!
