BDSM stands for bondage, discipline (or domination), sadism, and masochism. Here's what you can expect on r/bdsm. The subreddit is dedicated to BDSM porn, and redditors are in charge of finding the best gifs and videos of this discipline. Imagine a giant best of with professional and amateur BDSM content. It's a community that's been gathering nearly a million members since 2008 around the same fetish.
