Answer:
The author describes eating an ice cream cone as 'frozen dairy product ingestion'.
In the essay 'How to Eat an Ice-Cream Cone' the writer L. Rust Hill offers an ironic and humorous approach to eating an ice cream cone. He treats the topic as if it is a serious and essential part of the reader's knowledge. He uses formal vocabulary like 'quarantine', 'rigmarole', and 'contingency' in his description of eating ice cream. He presents the essay in the form of a how-to guide and shows how ridiculous the genre can be.
