If you don’t forward a chain letter (or email), it supposedly has a dire consequence. “I hate when I don’t forward a chain letter, and then I die the next day” is a jocular saying that has been printed on many images.
 
“RT @Fuh__Q Man.. I hate when I don’t forward a chain letter and then I die the next day. :(” was posted on Twitter by Christian on March 15, 2010.
 
   
Wikipedia: Chain letter
A chain letter is a message that attempts to convince the recipient to make a number of copies and pass them on to a certain number of recipients. The “chain” is an exponentially growing pyramid (a tree graph) that cannot be sustained indefinitely.
 
Common methods used in chain letters include emotionally manipulative stories, get-rich-quick pyramid schemes, and the exploitation of superstition to threaten the recipient. Originally, chain letters were letters sent by mail; today, chain letters are often sent electronically via email, social network sites, and text messages.
