It is worthy of noting that in Penelope's original statement her pronounciation of "ush" is different both times in the phrase "ush de ush"
The first sounding like "Oosh" and the second like "Uh-sh"
Many people who use the word "Ush" don't bother with being confused by this, but instead make a quick choice and pronounce the word however they wish. This has lead to criticism from renowned Linguists and a general dislike of the word amongst those who are not fans of Penelope Skinner.
In a recent poll of 15 to 35 year olds it was shown that 56 percent of the people questioned were infact users of the "Ush" word in some form or other. It is still debated whether the word has any place in modern society, as the controversial philosopher, Arnold Levoss, puts it- "Does "Ush" have any true meaning at all given the state of our current understanding of conciousness as a sentimental construct of inverted logic?"
