^(?!.*simpson.*).*skate-board.*$

(?!pattern)
is called a "zero-width negative look-ahead assertion."

You write the thing you NOT want before the thing you want.
To make sure that nothing "escapes" you have to use the anchors.
^.*<pattern>.*$
Otherwise a Title:
Simposon skate-board
would match. a "skate-board simpson" wouldn't match even without the anchors.
(Yes, Regular Expression can sometimes be a bit like a woman, unpredictable <g>)

Real Programmers consider "what you see is what you get" to be just as 
bad a concept in Text Editors as it is in women. No, the Real Programmer
wants a "you asked for it, you got it" text editor -- complicated, 
cryptic, powerful, unforgiving, dangerous.
