I like your “Onada.” LOL
I use “The Obamination.”
I always opt for using as few syllables as possible given the poor reading, reading comprehension and attention span of the average American—thanks to our Marxist-dominated public “education”.
Obamanation is good, too as it pretty much includes traitor in the name. In fact, I’m now adding the word “traitor” as appropriate when I discuss the Usurping Marxist/islamoterrorist occupying the WH.
