I noticed this word being used at theregister.co.uk . I'm pretty sure it's another way of saying script kid, maybe it's a bit more derogatory.
"...the emergence of AirSnort, and soon another similar tool called WEPcrack (which is still in development), are certain to deskill the process of breaking into wireless networks and in so doing open them up to s'kiddiots everywhere." - theregister.co.uk
A Skiddie or Script Kiddie is the term for an adolescent who takes a script from another website and uses it to hack without fully knowing what they are doing.
The key difference between a real hacker and a skiddie is that true hacking requires a large amount of skill, executing a script made by someone else requires little to no skill at all.
Being called a Skiddie or Script Kiddie is possibly the most offending insult a hacker can recieve.
The term Skiddie is often preceded by the word 'Dumb'.
