But it's not fit for print in this sub (Rogaine and Viagra ad spam as a source, what's funny about that? kek), so I'll refer to the link below.
What is Spam Poetry? (aka spoetry)
http://heatherhaley.com/hh2/?tag=spoetry
“It is unknown as to when the first spoem was started as several writers and bloggers have claimed to have created the form. However, it’s estimated that the idea began in 1999 as Satire Wire [1] held their first spam poetry writing contest in 2000 [2]. Animator Don Hertzfeldt began writing spam poems in his production journal in 2004 [[3]]. Translator Jorge Candeias wrote a “spoem” a day during a whole year, between the 5th of May 2003 and the 5th of May 2004, using spam subject lines as title and inspiration; these are in Portuguese, based on spam bylines mostly in English. The creation of spoetry is similar to William Burroughs’ cut-up technique in that individual subject lines of messages are pieced together in poetic form; making the creation of spoetry an exercise not in creativity as much as in having an eye for the unexpected. The end result can be crafted into any literary form the author desires: haiku, concrete, limerick, dada, and so on. Thus, spoetry is not a literary form but rather a means of creating poetry.”
