TSK TSK” is the sound created when you hit your tongue against the roof of your mouth / back of your teeth.
It is a sound most Indians resort to when they are speechless and / or wish to convey they are sorry about something, typically a bad news / the poor state of affairs in the country – death, famine, epidemic, the likes!

Sometimes represented as Tch Tch or Tut Tut, Tsk is more a vocal sound than an actual word, and "pronounced" by forming a T-sound, but then sucking lightly on the palate. People only say "Tisk tisk" as a parody of the actual sound, making fun of the act of disapproval or shaming.
