"Why This Kolaveri Di" is a popular Tamil song from the 2012 movie 3 , written and sung by actor Dhanush and composed by Anirudh Ravichander. The phrase "Why This Kolaveri Di" translates roughly to "Why this murderous rage, girl?" The song humorously expresses the frustration and heartbreak of love failure, using simple, quirky lyrics in "Tanglish" (a mix of Tamil and English). It became an internet sensation and viral hit due to its catchy tune, relatable theme, and unique mix of languages, reaching millions of views and widespread popularity across India and beyond. The song's tone mimics a Tamil person with limited English singing about heartbreak in a fun, light- hearted way rather than serious anger or violence. The song quickly rose to fame on social media and YouTube, becoming a cultural phenomenon with numerous parodies and covers. Its rise was helped by social media trends and its universal appeal about love and frustration, becoming a symbol of contemporary youth's expression in Tamil pop culture.
