acquehense
A fabricated word coined by Game Show Temple founder Michael Tiller that he claims means no, despite the fact that no dictionary anywhere nor any website found through a Google search has ever heard of that word. Perhaps a butchering of "acquiesce", but the context used in the example below makes that highly unlikely as it constitutes a double negative.
"Ok, you want to know when you'll see that request? I will say that I will NOT acquehense that request. It is therefore denied"
