Kanye West ain't happy about Kid Cudi accusing him of not writing his own lyrics ... and it sparked a vicious rant during 'Ye's Tampa concert.
You gotta watch ... but some of the highlights include: "I birthed you!" ... "I got called names before you, bro!" ... "I wore skinny jeans first!" ... and of course, "Respect the God!"
Kanye was responding to Cudder's own rant on Twitter ... calling out him and Drake for not working with him and for having other people write their lyrics.
It was a shocking move from Cudi because he walked away from Kanye's G.O.O.D. Music. Also, because ... Meek Mill.
Drake took a less dramatic approach, but also responded to Cudi Wednesday night in Oakland.
