Definition for
script kiddie by niffshack:
A True Fool. One to be looked down upon. They tend to use leet speak, but dont realize its true significance. They are usually 10-14 year old kids (or so) who think they are "1337 |-|4x0r5", but are really just trying to be cool.
They call themselves hackers (which is not the same as a cracker, a hacker is a programmer, a cracker is a person who breaks into computers), while they are neither hackers or crackers.
They use other peoples programs to do their simple "hacking", and usually end up getting caught.
Hackers are really cool people. Script kiddies are morons.
Examples:
Hacker: I just wrote my 30th module for the Linux kernel! Linus Torvalds emails me every day, he loves my code!
Cracker: I just broke into the CIA's webpage and replaced all occurances of the president's name with "Mr. Dumbass", It's funny as hell!
Script Kiddie: j0, ph00! I ju57 stolezored me a b0rkified wind0ze 3.1 b0xor. It r0x0rz my s0x0rz. I wundr if it g0tz Linux on it? Whutz Linux anywayz?
