I never heard of this phobia and didn’t know it existed and had a name. I was not online in 2005.
Trypophobia is a proposed phobia (intense, irrational fear, or anxiety) of irregular patterns or clusters of small holes or bumps. The condition is not officially recognized as a mental disorder, and is rarely referenced in scientific literature.
Although few studies have been done on trypophobia, researchers hypothesize that it is the result of a biological revulsion that associates trypophobic shapes with danger or disease, and may therefore have an evolutionary basis.
The term trypophobia is believed to have been coined by a participant in an online forum in 2005. Since then, the concept of trypophobia has become popular on social media.
