Sketchball?

Maureen Dowd uses the term "sketchball" in this context:

Rummy misses the point: we're supposed to be the good guys, the beacon of freedom. Our message is supposed to work because it has moral force, not because we pay some Lincoln Group sketchballs millions to plant propaganda in Iraqi newspapers and not because the press here plays down revelations of American torture. If the Bush crew hadn't distorted the truth to get to Iraq, it wouldn't need to distort the truth to succeed there.

I did a search on "sketchball." After half a dozen tries, I found:

Sketchball
a. A person that is so involved in drugs, alcohol, sex, and general debauchery above what is conceiveably possible.
b. A shady character.
c. Someone that appears to have no moral judgment, self-respect, or general hygiene to the point where he/she is a total laughingstock that must be avoided.
Holy crap man, he lives in Roxbury, obviously hes a sketchball.

She dumped him and went out with two other guys on the same day? Holy sketchball, batman!
