I received an e-mail including the following sentence:
I am not asking for a facetious grade change, just one that would allow me to pass.
What the writer means is that the request isn't frivolous or petty. This use sounds wrong to me, but the literal dictionary definition doesn't contradict it (the dictionary definition includes, for instance "flippant").
My question is whether this is a use typical in some situation or dialect I'm not familiar with, or if it's actually completely nonstandard.
