There are two versions (#2 is probably used more widely and more often):

1) A shortened version of the sentence: "Doninnit, trust me blood there's a Don in the place right now blood, doninnit."

2) "innit" is added onto the end of words and "Tron" is the first part of the word. Tron is a completely random word. Other words that sound appropriate can be used here.

Chanted by human infidels when superior robots enter the room. All must rise and chorus this cherubine verse 3 times to escape getting their skull pulped by the God of all robots, Robot Frank. Remember that we all live in The Matrix and inevitably will meet our demise if we don't cooperate with the machines. Neo is an eluded fantasy and he will bring the destruction fo the world. Frank forver.
"Troninnit, troninnit, troninnit, for the Lords of the Land, thy robots doth quoth."
