A subreddit where people who self harm go on to relate to others who have similar issues. Often times you will see memes (often self-deprecating) and rants. It's often shorted as r/MoS, and they have a certain lingo. For example, styrofoam (or 'styro') refers to the dermis layer of the skin, which is white and resembles styrofoam. Yeeting is the act of self harming, and yeeting bois/slicey bois is the tool they use to hurt themselves with. This subreddit is not for everyone.
