Re: Amateurs
When people use the term "script kiddie" they are generally implying that their own IT/haxing skillz are far better than said kiddie so you can look down at them with withering scorn at their abilities.
The same is true of the phrase "amateurs" , especially if accompanied by an exclamation mark. To use the phrase "amateurs" you are implying that you yourself have far better skills in the area applicable.
So to summarise , you are in fact bragging about how much of a better thief , fraud and money launderer you are *. Although shouting about it isnt one of the hallmarks of a true expert (i wouldnt have thought).
* .... unless done ironically for comedic value of course!
