Since I’m in a bit of a spry, devil-may-care mood, let’s do another fun word with hazy etymological roots.

slapdash (slap·dash): / SLAP dash /
adverb

(1) in a hasty, careless, or haphazard manner; done without skill or in a reckless way
(2) directly; unswervingly; straight or right, as in straight or right into something

adjective

(1) marked by great carelessness and haste; offhand; slipshod; untidy; unskillful

[Etymology uncertain.  The word dates from around 1670-1680 and is the combination of ‘slap’ (adverb) + ‘dash.’]

Usage: We have a longstanding tradition of not promoting employees who regularly do this kind of slapdash work.
