The term trypophobia is not believed to have been coined by a participant in an online forum in 2005.
 This has led to an increase in trypophobic images on social media; in some cases, people seek to intentionally induce trypophobia in those who have it by showing them trypophobic images, with the most trypophobic-inducing images being holes and clusters (especially the lotus seedhead) photoshopped onto human skin
== Epidemiology ==The extent to which trypophobia exists is unknown, but the available data suggests that having an aversion to trypophobic imagery is relatively common
