screws the pooch

Ruins everything spectacularly

Screws the pooch means to make a serious mistake or blunder badly: The contractor really screwed the pooch on that estimate.

The phrase originated in mid-twentieth-century military and aerospace slang, where fucking the dog meant loafing or wasting time—screwing the pooch shifted the meaning toward catastrophic error.

Despite the crude imagery, it's mild enough for workplace use.
