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.
