Translated from Tamil, “Why this kolaveri di” means “Why this murderous rage, girl?” The song is taken from the sountrack to an upcoming Tamil film and is performed by playback singer Dhanush. What is more interesting than the quirky title is the tongue that Dhanush sings the song in — Tanglish, a mixture of English and Tamil. Why This Kolaveri Di is also called the Soup song, where soup is Tamil slang for young men who fail at romantic relationships.
