What does essay mean in spanish?

Answer 1

As a familiar term of address, "ese" (pronounced like the English "essay") is roughly equivalent to "dude" in English.

This usage was popularized by the Cypress Hill Song "Insane in the Brain", which begins with the line "Who you tryin' to get crazy with, ese?". "Ese" is the Spanish name for the letter 'S'. It is possibly a reference to the Sureños, a Mexican street gang active in Southern California.
