A DISGRUNTLED state Labor MP has attacked his own Premier, saying Twitter makes him behave like a ''12-year-old with Tourettes''.

Paul McLeay's extraordinary comments extended to Prime Minister Kevin Rudd, whom he accused of ''perpetually spamming everyone on Facebook''.

His cyber spray has not only astonished party insiders but angered Tourette Syndrome Association president Robyn Latimer, who said such comments stigmatised sufferers.

A senior State Government source said the ''stupid'' comment illustrated why Mr McLeay had never made the frontbench. A spokeswoman for Premier Nathan Rees said Mr McLeay owed an apology to anyone he had offended.

''Other than that, this is so far down the list of the Premier's priorities that it doesn't warrant any response,'' she said.
