Fanking refers to sexual stimulation of a person's genitals whilst smoking a cigarette (fag), usually
to the point of orgasm and is usually conducted within a locked automobile.
The stimulation can be performed manually, by other types of bodily contact (short of
sexual intercourse), by use of objects or tools, or by some combination of these methods. Self fanking is a common form of
autoeroticism. Fanking with a partner, called mutual fanking, is also common.
Communal fanking in large groups over an extended period of time is collectively known as a fankathon, short for fanking marathon.
