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. The title of the song references a viral Facebook Messenger screenshot, popularized on Reddit, in which an Indian man, in broken English, demands nude photos, and, when his messages go unanswered, he posts bitch lasagna ( lasagna might have been an approximation to the parting phrase hasta lasagna, but without punctuation the post looked like he was calling her a bitch lasagna).
The two channels surpassed each other in subscriber count on a number of occasions in February, March, and then in April 2019, when PewDiePie declared an end to the 'subscribe to PewDiePie' meme and T-Series became the most-subscribed YouTube channel. During the competition, both channels gained a significant number of subscribers at a rapid rate, jumping from approximately 60 million to 100 million subscribers within a few months.
As a result, fans, along with celebrities and other YouTubers, showed their support for each channel by encouraging others to subscribe. 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.
