Sketchy Prick

One who seems untrustworthy, and/or dirty and/or clearly addicted to some sort of drug.
A sketchy prick would also be considered one who walks around in public, having an open conversation with themself.

Look at the Sketchy Prick over there.

Heads up, there's a mad sketchy prick coming this way.
