Drake was feeling real petty over the weekend!

On Saturday night, the Canadian rapper switched up the lyrics to his 2015 smash hit single “Know Yourself” — changing the lyrics “Then Kanye dropped” to “Then Kanye flopped” dissing Pusha T’s producer.

The diss was caught on video by fans, who shared the modified verse to social media. Adding insult to injury, Drake was on stage at The United Center in Chicago, West’s hometown.

It would appear Drake is referring to West’s latest album, Ye — which dropped on June 1. According to Billboard, it sold 208,000 equivalent album units on its first week, landing at No. 1 on the U.S. Billboard 200 and spawning singles “Yikes” and “All Mine” (both that placed in top 10 of the Billboard Hot 100).

Meanwhile, Drake released his own album, Scorpion, later that month. The LP also debuted at No. 1 on the U.S. Billboard 200 but sold 335,000 equivalent album units, Billboard reported. It’s since set records, with all 25 songs charting on the Billboard Hot 100. Three of those songs — “God’s Plan,” “Nice for What,” and “In My Feelings” — reached No. 1.
