Originally a Matrix reference about waking up to “the truth,” this got hijacked by edgy political corners of the internet. To be redpilled now usually means someone thinks they’ve seen through the lies of “the system” and suddenly everyone else is a sheep.

“Ever since he found that forum, he’s fully redpilled and giving election speeches at brunch.”
