Don't ever get on Kanye West's bad side.
Not surprisingly, Kanye West doesn't take Twitter slams lightly.
After rapper Kid Cudi called out both West and Drake in a few choice Twitter posts on Wednesday, implying that the two don't write their own music and employ multiple songwriters, West fired back with his own passionate onstage rant at his concert in Tampa, Florida.
In the middle of performing his song "I Don't Like," West, 39, abruptly stopped the music to put Cudi on blast.
"Kid Cudi, don't ever mention 'Ye name," he said as the audience cheered. "I birthed you! We all dealing with that emo sh*t all the time .... Don't ever mention 'Ye name."
"Don't try to say who I can do songs with," he added. "You mad 'cause I'm doing songs with Drake? Ain't nobody telling 'Ye who to do songs with! Respect the God!"
Kanye West signed Cudi to his G.O.O.D. Music label in 2008, but he left in 2013. The two collaborated on multiple songs together, including hits "Paranoid" and "All of the Lights."
"I'm so hurt. I feel so disrespected," West continued on Wednesday. "Kid Cudi, we're two black men in a racist world. I wore skinny jeans first. I got called names before you, bruh. Why y'all got to come at me?"
"I'm out here fighting for y'all: creatives, artists, independent thinkers," he added. "Don’t never mention my name in a bad manner. None of y'all!"
Drake also appeared to address Cudi's diss in a more light-hearted way at his own show on Wednesday in Oakland, California, cracking, "Boy, you getting way too high, you need to cud-ittttt."
The latest beef started when Cudi, 32, publicly took shots at the two rappers earlier in the day.
"Everyone thinks they're soooo great. Talkin top 5 and be having 30 people write songs for them," the "Pursuit of Happiness" rapper tweeted. "The fake ones won't be lasting too much longer. I'm the one they worry about cause they know I don't give a f**k about the corny sh*t they do."
"My tweets apply to who they apply," he continued. "Ye, Drake, whoever. These ni**as dont give a f**k about me. And they ain't f**kin with me. ... I've been loyal to those who haven't been to me and that ends now. Now I'm your threat."

West and Cudi have been notably close in the past. In January, West accused Wiz Khalifa of stealing his "whole sh*t from Cudi" when he went on his own infamous Twitter rant against the "See You Again" rapper.
