screwed the pooch

Made critical error

Screwed the pooch means to make a serious mistake or blunder badly: The IT department really screwed the pooch when they deleted the backup files.

The phrase originated in mid-20th-century American military and aerospace slang, suggesting a failure so egregious it's almost obscene.

Despite the crude imagery, it's now common in casual speech and even professional settings.
