Tekashi 6ix9ine won't let up on Meek Mill.  Yesterday, he said the Philly rapper was his inferior because Meek has never scored a number one, like 6ix9ine just did with Meek's ex Nicki Minaj.

This afternoon, Meek Mill went Twitter fingers and sent out a threat that certainly seems directed at 6ix9ine.

"I will catch you lacking 4 years from now on some cool sh*t lol soon as you thought it was over," Meek typed.

Do you think Meek has the patience to wait four years for revenge and do you think 6ix9ine will still be around in four years to be caught lacking? 

Here's what 6i9ine said about Meek and others yesterday:

"Today I'm number one in the world and I just want to address some things, "6ix9ine said. "I got a list. Let's start at the top. Future, you've been rapping over a decade, if not close to a decade. You have many Drake features my friend, and you never went number one. Mr. Meek Mills, since 2011, close to a decade. You never went number one either. The Lil Boys, the little guys in the game. Lil Durk, pretty local, you never went number one sir. G-Herbo, I don't think you entered the top 100, I could be wrong. Gucci Mane -- nope, never been number one either sir. Trippie Redd, we signed to the same label, never went number one. Every New York rapper that's a male that's not old, you never been number one."
