Top Definition
the annoying tendency for any grocery or convenience store beer case to be 99% filled with different brands of the same bland undrinkable 'American pilsner': Budwieser, Miller, Coors, etc.,with the remaining 1% contaning poor examples of imported beers like Heiniken or corona. Often the only ale offering is
Bass.
I went to the store wanting some DunkelWiesen but was disapointed to find a bad case of Pilsner Proliferation.
