As a side note, what I liked about Steve Jobs is that he almost never used over-the-top adjectives to describe the products he was demonstrating. Rather, he used words like "cool" and "neat." This made him sound a lot more credible and convincing.
I'm not really an Apple guy, though, so it may be a misperception on my part.
My favourite over-the-top Jobs-ism was "Insanely Great." "Wicked Fast" comes in second. He may have overused these terms, but some of Apple's products hit the mark. I really think the Macintosh SE and first iPhone ware insanely great products.
