liegument

An argument based on a lie. Used if you want to argue a point to somebody, but you don't have any real evidence, so you just lie about it and hope nobody notices. Used often by students trying to convince their teachers that all their rules are completely pointless.
Simon: What are you doing?!

Kevin: Oh, just making up some evidence for my liegument.
