词源
The phrase 'blow it' emerged in the early 20th century as an extension of the verb 'blow,' which has long meant 'to ruin or destroy' in informal contexts (e.g., 'blow one's chance'). The idiomatic use became popular in American English slang.
用法说明
Used primarily in spoken English and informal writing. Often implies a preventable failure rather than an inevitable one. Can sound harsh if directed at someone; softer alternatives include 'mess up' or 'screw up.'
