1.
Used to describe a place that is shady, iffy or just generally makes one feel unsafe.

The word was created by a passer-by to describe Vancouver's shady east side and grew like wildfire across the nations.
Going into a poor area that doesn't feel safe is sketchy.
Not down with this guy he is super sketchy.
