To attempt to explain something you don't understand using language you don't quite grasp to people who aren't listening anyway, because they've already done their own research.
Uncle Dewey had to Magasplain what FOTUS means without using the wordfelon.
An acronym or short phrase coined by Donald Trump and used by MAGA voters. The MAGAism is an oversimplified token of a complex issue or something with little meaning, created for the uneducated masses to use instead of dialogue. Examples are: TDS, DEI, Enemy from Within, WOKE, Illegal Criminals, Deep State and others.
Rather than discuss Trump's character, he finished the chat with "TDS". Hate when they end with a MAGAism.
