MGTOW or "Men Going Their Own Way". To oversimplify it, it's a loose "movement" of guys who have giving up on the idea of marriage and dating. Some have been in relationships before and have gotten burned, some have never even been in a relationship. Some are guys who have decided they just don't want to deal with the headaches of modern dating, but others are just crazed misogynists.
What I find interesting is some of these guys seem to really think that they are really on the crest of a political wave and that the women are nervous since the men have woken up. And that there's a revolution coming.
