Attested: I first encountered this term in September of 1998, spoken by my chemistry professor.

Okies (noun)
Oak-ees; rhymes with rookies; /o@wkiz/
Definition: The nickname given to the Okenshields Dining Hall in Cornell University.
Attested: This is a very common term and I cannot remember a specific instance where I heard this term. It was most likely said when I was deciding where to eat and somebody suggested, Okies?
Example: "Let's go to eat at Okies tonight."
Etymology: This is a very unique term and I have never heard it used outside of Cornell University. It is just one example of the several nicknames given to the various dining halls in Cornell. For example, the Robert Percell Dining Hall is sometimes referred to as Bobs. The derivation of these terms comes from an abbreviation of their actual names.
