actual annoying phrase "flesh out." When someone uses the phrase "flush out," I know they are extra worthy of heaps of scorn.
Other awful, awful words:
"laser focused"
"pivot"
"lean in"
"circle back"
"rightsize"
"Adjustments," in lieu of "changes" or "cuts" (BTW the Church uses this word "adjustments" all the time, and it drives me bonkers)
"deep dive"
"soup to nuts"
"drill down"
