After the late Matthew Dutkiewicz, "Duck Law" is anything one may say at random times that has got to be (by popular decision) an utter lie and made up fictional subject to convey a point that is so untrue it has got to be true. Hence it is "Duck Law". "Duck Law" only works through persistent argument.

Leland: What? No you don't

Matt: Ya you do, all the time, it never fails bro

Leland: Your not ganna win!

Brendan: Don't argue with him.. He's pulling some sort of "Duck Law" here
