A
red piller is someone who is proficient (or at least thinks that they are) in the act of redpilling. In most cases, the
red piller is politically motivated and attempts to lead their target to their side of the political spectrum through a variety of mediums- most commonly
memes, (edgy) jokes, and (mis)quotes.
While there are examples of
red pillers all over the political spectrum, they are most prevalent on the far left and
right, along with fringe groups of fascists, communists, or anarchists -recently being used nearly exclusively by the right wing.
The "red pill" term comes from
The Matrix, in which a character chose between a blue pill and a red pill, where the blue pill would let them live freely and without knowledge of the inner workings of their world, and the red pill would allow them to "wake up" from their ignorance, and learn the "truth."
Person 1: "Wow, this guy's
woke, they must be a
red piller."
Person 2: "Nah, they're just
cringe."
