"Bitch Lasagna" (stylized in all lowercase), originally named "T-Series Diss Track", is a song by Swedish YouTuber PewDiePie in collaboration with Dutch music producer Party in Backyard.

[18][19] In the song, PewDiePie insults T-Series and their video content, makes references to contemporary Indian stereotypes and accuses the company of using subscriber bots to gain fake subscriptions.

[20][21] As PewDiePie vs T-Series coverage grew in the mainstream media, news organizations covered "Bitch Lasagna" for its role in the feud.

T-Series asserted the tracks were "defamatory, disparaging, insulting, and offensive" and that the songs contained "repeated comments... abusive, vulgar, and also racist in nature."
