Slapdash is formed from "slap" (of uncertain origin, possibly imitative of the sound made) and "dash" (from Middle English "dashe", meaning to strike or hit). The word describes something done in a hasty or careless manner, as if struck or dashed together without thought.
Think of something done quickly and carelessly, like a 'slap' that makes a sound and a 'dash' that implies speed — this helps you remember that 'slapdash' means done hastily and without care.
