One of the men accused of murdering a Norfolk man texted his friend "I am now a man" shortly after the attack, a court has heard.
Steven Murphy, 45, was found with 16 stab wounds in Fakenham in October 2009, by his mother.
Alexander Dewar, 24, and Andrew Cameron, 28, both from Blackpool, deny the murder.
Norwich Crown Court heard Mr Dewar had texted a friend saying someone had been killed and that he was "now a man".
Ali Kemal, who lives in Blackpool, said in texts Mr Dewar said he could not meet Mr Kemal one night as he had "a job in Norfolk, an unpleasant one" and that a man had been killed.
Mr Kemal said there was no mention about how the person was killed.
"Deep down I thought it was a wind up," he said.
Mr Murphy's mother found his body when she took him clean washing on 1 October.
Mr Cameron and his father James, 53, of Felixstowe, Suffolk, both deny conspiracy to cause Mr Murphy's grievous bodily harm between 20 May and 2 October last year.
Karim Khalil, prosecuting, told the court the killing took place after a feud developed between James Cameron and Mr Murphy over the victim's friendship with a woman, Julienne Dowling.
The case continues.
