Abbreviation of the word forward used by most e-mail programmes. A forwarded message is a message that has been sent on, usually in it's original form, to a different address. About 95% of these messages appear to be irritatingly twee stories with threats at the bottom (i.e. if you don't send this e-mail to 27 people in the next 42 seconds all your family will die slow, painful deaths at the hands of mutant squirrels).

Also an abbreviation for front wheel drive.
