An early recorded use of slapdash comes from 17th-century British poet and dramatist John Dryden, who used it as an adverb in his play The Kind Keeper. "Down I put the notes slap-dash," he wrote. The Oxford English Dictionary defines this sense, in part, as "with, or as with, a slap and a dash," perhaps suggesting the notion of an action (such as painting) performed with quick, imprecise movements. The adjective slapdash is familiar today describing something done in a hasty, careless, or haphazard manner.
the police department's investigation of the charges against the mayor was slapdash and not very thorough
