I was gonna spell it "snark-o-meter" but then I realized that sounds like something that makes snark... I want it to be something that measures or detects snark! So, it's pronounced "snark-aww-met-ter".
I've been so sick of snark lately that I think my snarkometer is a little extra sensitive... picks up snark even when snark is not really there. Makes for a lot of "calm yourself, Mrs. Wagon!" moments!
