Someone urinates (or, occasionally, defecates) in a swimming pool, either by accident or on purpose. If it's an accident, it's also a Potty Failure. Usually in cases of urinating on purpose, the offender believes that because the water is chlorinated it will clean itself... or they're that much of a jerkass that they just don't care. This is almost always Played for Laughs, but it can be Played for Drama if needed. This is one way to put some Toilet Humor into a work.
