to lie about something, not in a sense of not telling the truth, but more like you were kidding. Not to be confused with the act of lying (i.e. lying about your income) more of a means to either cover up something you just said but shouldn't have, or to just confuse someone else. Can also be pronounced with massive emphasis on the I... as in EYE lie.
You are a such an idiot, i lie!
Oh, i ate your sandwich... uhh, i lie
