Hard kink

Hard kinks are kinks that often overlap with those in the BDSM community but can go further in certain scenarios or simply suggest a different scene than what is typically considered for more intense fetishes. Often, hard kinks require greater mental energy or emotional energy per scene or play off of a specific taboo.

Most often used on twitter in NSFW circles, it is a concise way to explain that the user isn't into vanilla sex but isn't looking for a dungeon with leather and sex swings. Certain users may opt to say "harder kinks" as a means of depicting a greater level intensity. It can range from choking, spanking/slapping, degradation/humiliation, all the way to CNC (consensual non-consent/rape fantasy), stalking fantasy, violence fantasy, incest fantasy, etc.
