Pshhhhhhhhhh

Why is it that when people see a "chushuva" or even a not so "chushuva" person get a kibud they have a natural inclination to make a rude sound.

"Yaamod Yankel ben Zalman, Shlishi"

Pshhhhhhhhhhhhhhhhhhh.

What does a sound reminding us of the act of urination have to do with getting a kibud?

This question has been asked by numerous rabbis (I use that term loosely considering the current state of the cheif rabbanite in Israel) and has been answered as follows:
1. I'm so very impressed that my neighbor, the am haaretz, has been given shlishi that I have literally wet my pants. In recognition of this, I make a peepee sound.
2. My neighbor has recently had prostate surgery and needs all the encouragement he can get.
3. Pshhhhh does sound like peeing but it also sounds like something deflating. We direct this sound at our neigbor to let him know that he shouldn't let the kavod go to his head --- he should deflate his ego.
4. In a  similr  vein, it is brought down in a book written by some guy with a long beard that kibudim are typically given to chushuva people. Of course these people are generally no more chushuv than my belly button lint so it has become minhag yisroel to let them no that despite this kibud they are getting, they are still a bunch of pishers.
5. A pishing sound is better than a flatulation sound.
