The act, practice, or result of doing something badly or clumsily; bungling work.
From 'botch' (to do or repair something badly) plus the suffix '-ery,' meaning 'practice,' 'behavior,' or 'collection of things.' The suffix appears in words like 'bakery' and 'bravery.'
Medieval tailors who did poor repair work were the original 'botchers,' and their terrible stitching jobs became so infamous that the word stuck around for 500+ years to describe any kind of sloppy work.
