It’s official; Kanye West is at war with Wiz Khalifa.

Today Khalifa criticized West for changing his upcoming album title from SWISH to WAVES.

“Please don’t take the wave,” Khalifa wrote on Twitter. “Max B is the wavy one. He created the wave. There is no wave without him.”

“He’s the reason I sing on all my songs,” he continued. “That’s the wave. If theres nothing wit that sound ITS NOT WAVY.”

West immediately shot back at Khalifah, in one of his best ever Twitter rants.
