Omorashi is a Japanese word derived from two other Japanese words, omo and rashi, which can be translated to mean “wet one’s pants”. It has a variety of interpretations, many of which overlap in some degree, though it has primarily two distinct meanings. The most common interpretation of omorashi refers to a sexual fetish in which a person is aroused by the feeling of a full bladder and the need to urinate. This particular fetish is known as omorashi yamai in Japan and is practiced in the form of games, hobbies, and forms of entertainment that involve filling one’s bladder to an uncomfortable point and struggling not to urinate. The second interpretation of omorashi is a non-sexual form of aroused excitement, similar to the feeling of needing to use the bathroom when one has held it for too long. This feeling is usually used in reference to something that is thrilling or nerve-wracking, such as a difficult exam or an exciting ride at an amusement park. This interpretation is often associated with the phrase “ants-in-the-pants”.
