Totally Wack

An editorial in today's Commercial Appeal contains the following passage:

It's a long story, and it's complicated, but the bottom line is simple: If there's any way to stay off Interstate 240 at Walnut Grove, by all means do it.

The Walnut Grove improvement project is totally wack right now -- at a stage that goes beyond mere traffic jamming.

Is this any way for a "world class" city newspaper to write? I know the paper long ago made its peace with using contractions to sound more like its readers, but "totally wack?"

Do these people even look up as their car careers over the road's edge?
