Kid Cudi isn't taking Drake's recent jab at his mental health issues lightly.
After Drake released his track "Two Birds, One Stone" on Sunday -- in which he calls Cudi's depression a "phase" -- Cudi responded via Twitter on Friday with some very NSFW language.
"Say it to face, p***y," Cudi, 32, tweeted. "You think it's a game. I wanna see you say it to my face. I'll be out soon. Promise."
WATCH: Kanye West Goes Off on Kid Cudi Onstage After Rapper's Twitter Diss: 'Don't Ever Mention Ye's Name! I Birthed You!'
Earlier this month, the "Soundtrack 2 My Life" rapper checked into rehab for depression and suicidal urges. “It took me awhile to get to this place of commitment, but it is something I have to do for myself, my family, my best friend/daughter and all of you, my fans," the rapper shared in an emotional Facebook post. "I am not at peace. I haven't been since you've known me. If I didn't come here, I would've done something to myself."
The move came after Cudi publicly slammed both Drake and his onetime mentor, Kanye West, last month on Twitter, implying that the two don't write their own music and employ multiple songwriters. Kanye responded by going off on Cudi during his concert in Tampa, Florida.
"Kid Cudi, don't ever mention 'Ye name," West 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."
Kanye has since squashed the beef, calling Cudi his "brother" during a later show in Houston, Texas.
"I just wanted to take time out to say Kid Cudi is my brother and I hope he's doing well," he told the audience.

The same, however, can't be said for 30-year-old Drake. The "Summer Sixteen" rapper reignited his feud with Cudi in his new track, rapping, "My numbers are out of the world, no wonder they got me feeling so alienated/You were the man on the moon, now you go through your phases/Live for the angry and famous."
Man on the Moon: The End of Day is the title of Cudi's debut album, which he released in 2009.
