Trypophobia: an irrational fear of small holes or clusters of small holes and bumps. It can manifest as feelings of unpleasantness, unease, disgust, or revulsion when looking at areas of clustered small holes. Examples of images that could provoke trypophobic reactions include a honeycomb, bubble bath, or lotus seed pod. Like other phobias, the exact cause of trypophobia is not well understood. It is not officially recognized as a mental or psychological disorder.
