Dicks out for Harambe
The dicks out for Harambe memes started pretty soon after his death, and it spread like wildfire around the internet. There’s even an entire thread on Reddit exploring why this is a thing, and where it came from.
At the end of the day, no one is really sure why this became such a cultural phenomenon. The only sensible explanation anyone had was that it came from the ironic desire to mourn his death — and it seems like the only way that anyone with a Twitter account knows how to mourn someone is to do it ironically.
