What is the definition of Benchmark Infection?

A 'benchmark infection' is like the worst, most pervasive cold that's been passed around in office cubicles for years - the kind of cold that everyone knows by name, but no one talks about, because it's so universally annoying and contagious that even the best team members start to wonder if they're secretly part of the viral epidemic.

Example sentence: "The benchmark infection in our office's Wi-Fi was a sneezy, hacky, and perpetually lousy virus named 'CoffeeLoverVirus,' which spread faster than a sushi platter at a Tokyo sushi bar!"
