"Lotus pod breasts" (also called "nipple bugs" on the Internet) refer to women's breast ulcers caused by myiasis. The spot in the middle of the chest is covered with black stuff, which looks like lotus pods. The real culprit causing breast ulcers is a carnivorous fly called Tumbu fly. Myiasis may also be a cause of chest ulcers in the habitat of the shield fly. However, chest ulcers caused by shield flies are extremely rare.
This is one of the "words you should never search for". Others include girls committing suicide in the bathroom for twenty days, empty fingers, lotus pods, tick dogs, giant viewing pictures, etc. If you really want to search, be sure to search before eating, otherwise you will spit it out.
