The retort to Nikhil's essay is quite amusing, but it unfortunately misses the point. While it is true that women may not be able to experience urinating while standing up, they still understand the process and can make an educated guess as to what transpires. Furthermore, the "ready, aim, fire" metaphor is more than just an overstatement; it provides insight into the typically orderly and dignified manner of the male urination process.
The retort is correct in saying that men often take a more pragmatic approach to urinating. But this isn't necessarily a matter of efficiency, it's about accuracy and getting the job done right. Men must often use techniques such as "spray and pray" in order to make sure they don't miss or go outside of their restroom's target location, which can be awkward in public restrooms.
In other words, while men may have had to develop quicker and more efficient techniques for urinating, this doesn't mean that their natural inclination isn't the "ready, aim, fire" approach. This is why Nikhil's original essay was right - the popular female conception of male urination process is one of law & order, decency & decorum. UrRong;the "spray and pray" technique is just a means to an end, ultimately allowing men to retain their sense of order, decency, and organization while still getting the job done quickly.
At the end of the day, there's absolutely nothing wrong with a little "spray and pray" from time to time. After all, everybody does it differently, but everybody does it!
