Tekashi 6ix9ine is on the comeback trail.

He's already set the bar on his trolling pretty high, so he needs a new gimmick.

In the track he's been previewing he has one, claiming he personally shot and robbed other rappers.

"I shot you, I robbed you, and y'all ain't do nothing back/Remember that, n*ggas lack, y'all ain't do nothing back but make tracks/sick dick n*gga, eat my sack/I shot at all y'all rappers, real life, no cap/The feds charged me for that, a whole f*cking case," Snitch9 rapped.

We don't know exactly who he is talking about, but 6ix9ine was implicated in shooting and/or robbing incidents involving Chief Keef, Trippie Redd, Casanova, and the Prince family.

Funk Flex has said 6ix9ine's new music slaps  -- but he's not going to play it.  What do you think of the return of rap's clown prince?
