The Brief: "Wake up sheeple" is a call for people to become aware of something that is not obvious or mainstream.

DEEP DIVE
Sheeple is a combination of the words sheep and people, referring to people who are lemmings and do not think for themselves. The phrase “wake up sheeple” can be used very seriously or more jokingly to bring something attention to the complacent masses. Often used in a political context, sheeple and NPC‘s are near-synonyms, but with different memetic contexts.
