Explain a 'script kid' like I'm 5

[RwkY]

Usually a script kiddie is a junior programmer/developer who can copy-paste code from different sources and "mod" it to do it's pleasing; the idea behind this is that he (being the person) does not understand the code, he just uses his intuition/basic skills to modify.

Another referring concept is a person who uses software made by others (this was popular in the 2000s-2010s) when there were many cracks/mods/hacks/etc. and this person would use them in his advantages.

Also script kiddies do a lot of trial & error when (if) writing stuff.
