Pet peeve:  Corporate Speak — especially when it spills over into the non-corporate vernacular.

Current favorite:  “reach out to.”

Like, “Have you reached out to Kevin to discuss his progress on the Smith project?”

What the heck is wrong with “Have you discussed the Smith project with Kevin?”

Or, “Have you talked to Kevin about the Smith project?”

Or, “Did you contact Kevin regarding the Smith project?”

Or, “Did you call Kevin for a review around the deadlines on the Smith project?”

Oooops.  Now I’m doing it.
