Something created to scare people by telling them something bad will happen if they don't send it to the desired amount of people. It is sent on by stupid vunerable people.
A recent example:
Sorry dont open in front of parents 5 ppl acually got killed by not sending this this piece of mail the creator of this mail has a program that will track down everyone who sent this and whoever that didnt send this will die cuz this program can actually track down ur address Send this to 15 people
no send bks
(How does the writer know that it has killed 5 people before he/she has even sent it?)
