The feeling you get when you obtain one of the following: revenge, orgasm, college degree, a really hot chick's/dude's phone #
(revenge/orgasm) I was satisfied after I came for the 4th time that night, afterall, I was fucking my girlfriends sister after I found out my girlfriend cheated on me.
(degree/phone#) I was showing off my college degree at work and this hot chick gave me her number.
If you are a man, you need no example. If you are a woman, an example would be like trying to describe sound to a deaf person. Discontinue trying to receive satisfaction.
A sense of fulfillment/contentment after achieving a goal. Also, the look on David Cook's face with that infamous grin after doing something particularly well. Usually sexually related.
The satisfaction I felt after that mind-blowing sex cannot be described or contained by any word.
