David Sasaki shares viral videos and social media memes from Mexico to show how “the meme has been embraced by a Mexican middle class as a tool to confront the impunity of the country’s elite.” For example:

In the same way that literature inevitably builds on the books of the past, memes in Mexico are often inspired by their predecessors. The week after subway riders protested the fare hike, leftist legislators rallied against the proposed energy reform bill, which allows private investment in Pemex, the state oil monopoly. For some reason, one of these legislators decided to strip down to his undies in protest. Twitter users immediately dubbed this decision “#PosMeEncuero,” or “well, then, I’ll just get naked.” It’s a playful example of how Mexicans creatively address their feelings of powerlessness.

The almost-naked legislator then inspired the protesters of the metro fare hike who not only jumped the turnstiles, but did so in their underwear.
