The ultimate Jackass. Everyone knows at least one of these. Will gladly accept credit for others accomplishments, usually full of themselves for no reason, and tend to have exceptional manipulative skills. Can often be seen reading poetry at Starbucks.
one example of a group of Jack Of All Asses would be the "earth lovers" who attend those 3 day hippie music festivals, and spend the whole time getting high as a form of "protest".
