It is, I suppose, a pun on an obscure reference. You Rage You Lose is an old internet thing where you post pictures or videos of infuriating people being infuriating and try to make the other people rage, at which point, I guess, they lose.

You Rach You Lose has become vernacular around my household for things that will make me personally insufferable to talk to for a while, such as anti-gay or anti-woman legislation, the equating of higher test scores with better education, jokes about women liking shoes and not liking sex, or assertions that the internet is a wasteland devoid of good writing or human connection.
