Plural form; unpleasant or offensive things, people, or matters.
From disagreeable (adjective) nominalized as a plural noun. A less common usage that treats disagreeable things as countable items.
Using disagreeables as a noun is charmingly old-fashioned—18th-century writers would refer to 'the disagreeables of winter travel' or 'life's various disagreeables,' making an adjective into a noun-like a verbal wink.
