Just days after Tory Lanez called himself the “best rapper alive,” Lil Pump is making his own claim to the throne.

Taking to Twitter, the 18-year-old rapper set off a firestorm with his bold declaration. “It’s scientifically proven that I’m the most lyrical rapper of all time,” he tweeted on Monday night (Jan. 28).

Social media promptly reacted with a series of memes that mocked his claim.

Pump, who is known for trolling, is in promo mode as he gears up to release his sophomore album Harverd Dropout on Feb. 22. He recently released his new single “Butterfly Doors” along with a video.

In April, he will perform at Coachella alongside Gucci Mane and Smokepurpp as part of the Gucci Gang set.
