Pissing contest

A pissing contest, or pissing match, is a game in which participants compete to see who can urinate the highest, the farthest, or the most accurately. Although the practice is often associated with adolescent boys, women have been known to play the game, and there are literary depictions of adults competing in it. Since the 1940s the term has been used as a slang idiomatic phrase describing contests that are "futile or purposeless", especially if waged in a "conspicuously aggressive manner". As a metaphor it is used figuratively to characterise ego-driven battling in a pejorative or facetious manner that is often considered vulgar. The image of two people urinating on each other has also been offered as a source of the phrase.
