Blackpill is about realizing nothing matters and there is nothing you can do that will change anything, it depraves you of all positive thought and makes you want to get some sort of meaning out of this limited time we have. Basically extreme nihilism.

The Blackpill philosophy also argues that physical attractiveness is the most critical factor in determining men's dating success, especially in modern Western countries. A man's money, status, and social skills are argued to be other factors of secondary importance, which is known as LMS theory. An expanded or alternate definition proposes that a man's dating and life outcomes generally rely on genetically determined traits. As a consequence of these beliefs, blackpillers often argue that men's dating issues require systematic rather than individual solutions, if there is any solution at all for the most disadvantaged males. Someone who holds a certain amount of blackpill beliefs is called a blackpiller or blackpilled.
