In mid-to-late 2018, the subscriber count of the Indian music label T-Series rapidly approached that of Swedish YouTuber and web comedian PewDiePie, who at the time was the most-subscribed user on YouTube. As of October 2023, the song has accumulated over 317 million views on YouTube, making it the most-viewed video on PewDiePie's YouTube channel. The song was first released with an accompanying music video on 5 October 2018, and was renamed and re-released to music platforms on 6 November 2018.

The song was one of the first events in the PewDiePie vs T-Series competition, in which the two channels competed for the title of the most-subscribed YouTube channel. The song satirizes Indian music label T-Series, as a response to predictions that T-Series would surpass PewDiePie in terms of subscriber count. ' Bitch Lasagna' (stylized in all lowercase), originally named ' T- Series Diss Track', is a song by Swedish YouTuber and comedian PewDiePie in collaboration with Dutch music producer Party In Backyard.
