Humpty's Law
From Fandom wank wiki
This page details a Jurisimprudence law.
Proposed here by jfpbookworm
When someone uses a dictionary to tell someone else what they really meant, all meaningful discussion ceases, to be replaced with arguments over whether the definition is correct.
Corollary 1: When someone ignores a dictionary definition to use etymology or idiolect to tell someone what they really meant, all meaningful discussion ceases and the aspiring linguist loses.
[edit]
Exemption proposed by pyratejenni
Unless the argument in question is about the meaning or origin of words or phrases. Then the person who pulls out the Oxford English Dictionary wins.
