漏尿（日语：お漏らし／おもらし／オモラシ；罗马化：omorashi）是主要流行于日本的恋物次文化，借由自己尿急或因他人尿急而引起性刺激。对这样的恋物者而言，当他人因憋不住而尿失禁时就是他们性高潮的时刻。在日本海外，漏尿癖和尿色情通常没有什么分别。对西方人而言，如果他们要分清这两者的异同的话，他们就使用膀胱绝望（bladder desperation）或尿裤子（panty wetting）等词语。在日文里，「お漏らし」一词本身就有「泄漏」的涵义，常以罗马字母拼写成omorashi。

Omorashi(おもらし / オモラシ / お漏らし) is a fetish subculture recognized predominantly in Japan, in which participants experience arousal from having a full bladder or arousal for seeing someone else experiencing the feeling of a full bladder. Outside Japan, it is not usually distinguished from urolagnia (urine fetish), though they are different things. Westerners who do make the distinction commonly use phrases such as "bladder desperation" or "panty wetting." The Japanese language term from which the subculture's name is derived means "to wet oneself," literally translated, "leaking." The word is also occasionally romanized as "omorasi" in the Kunrei-shiki romanization system.
