to commit perjury In the specific context used, the word seems to carry an undercurrent of deceptiveness that is perhaps not present with perjury. Whereas perjury may be the responsibility of a witness alone, the act of testilieing occurs at the behest of counsel. I got the feeling that the screenwriters would have used the word perjury, but wanted to make the dialog more interesting, so they coined a new word for the occasion. This is the only time I have heard this word; as far as I can tell, the screenwriters for Law & Order coined it when they wrote the script (though the formation seems obvious enough that it has no doubt been used before).
