truly stands for I Owe Unto.
as in i owe unto you this amount.
it is really just an expresion nowadays not really used because people as a whole cannot be trusted to pay debts ot just plain trusted. this is not urban but i saw someone else post this "word" and obviously hadnt a freakin clue what the true meaning is.
