orrissism
A statement made with deliberate intent to deceive, while utilizing some type of deceptive element, such as a double meaning or including some element of truth; enabling the specific meaning to be denied if the statement is challenged. This type of ambiguity is one of the most dangerous types of lies, as often times it is difficult to detect and it gives the person who is making the claim justification for the falsehood while minimizing the consequence if discovered.
John rarely outright lies, he is more likely to use an Orrissism or shift blame all together.
