According to the search results, a gooch is a slang term for the perineum, which is the small patch of skin located between the ball sack and anus. It is also known as the grundle, taint, or chad. This area is super sensitive and has a ton of nerve endings, which makes it an erogenous zone for some people. The term "gooch" is believed to be a play off the word "cooch," which refers to a womans vagina. The gooch forms a foundation that helps support the pelvic floor muscles to hold organs like the bladder and colon in place. While people have different names for this area, it is important to keep it clean and hygienic to avoid infections and unpleasant odors.
