gorn, v: The act of vandalising another person's computer whilst they are absent through lurid messages on their instant messenger and other chat programs (eg. mIRC, DC++), changing desktop backgrounds, and setting internet homepages to give the impression that the user is partial to homoerotic material and has homosexual tendancies. A portmanteau of the words "gay" and "porn". Orginated from Mt Gravatt College, Griffith University, Brisbane, Australia (circa: late 2005).
