SEO: Google description!?

How do I change the Google desciprion:
I’m using All in one SEO:
Zigges Frisörer
http://www.ziggesfrisorer.se/‎
“craps online is one of the best stress buster games in the virtual world. pai gow poker online allow high rollers to win massive amounts worth million dollars.”

I did enter all SEO setting correctly and I can find the “crappy” text above.
