Tsk Tsk

1/ I disapprove; 2/ You've been naughty; 3/ What a shame; 4/ How embarrassing for you; 5/ Isn't life unfair sometimes! 6/ I commiserate with your sadness/suffering/ill treatment. 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.
