The meme comes after the moon eclipsed the sun on Monday and it shows Trump eclipsing and blocking former President Obama. He captioned it: "The Best Eclipse Ever."
They went on to point out that if Trump had really thought about it, he'll realise that it means he (the moon) is blocking the world's source of light and life by blocking Obama (the sun).
Social media users responded with by creating another meme where Obama's face eclipsed Trump's.
