subtrend

noun

1. A trend that is part of a larger trend.

   “This year, there is a small but substantial subtrend. Instead of urging senior executives to take on lofty objectives -- like devising new strategies or creating a new corporate culture -- these books tell managers to concentrate on smaller or more specific tasks.”

   “Related subtrends such as balletcore, Barbiecore and regency-core have drawn criticism for hypersexualising innocence and encouraging women to dress for the male gaze.”
