Jay (slang), from Wikipedia, the free encyclopedia:

Jay is an old-fashioned term for a dull or ignorant person. It survives today in the term Jaywalking.

Its currency in the early 1900s can be gauged by this portion of the popular title song of a George M. Cohan musical play of 1905, Forty-five Minutes from Broadway:

Oh, what a fine bunch of reubens [1]
Oh, what a jay atmosphere;
They have whiskers like hay,
And imagine Broadway
Only forty-five minutes from here!
