To spoil or ruin something through clumsy work; to botch badly.
From 'be-' intensifying prefix plus 'botch' (to repair badly), origin possibly from French 'bocher.' The prefix amplifies the sense of comprehensive failure.
Adding 'be-' to 'botch' makes it even worse—not just a single mistake but a thorough, comprehensive messing-up. It's how people intensify complaints: 'You bebotched the whole project!'
