  Quotations
  Very little exists in the annals of the interwebs about Tostitos Hint of Lime. Many nights I’ve sucked down crusty mossed fingertips and typed away in a green-out (like a blackout, but from eating too much Tostitos Hint of Lime), searching for a like-minded fanclub, historical taxonomy, or even a press release.

3. (taxonomy, uncountable) The science of finding, describing, classifying and naming organisms.
