What is "orale"

Órale is a common Spanish interjection in Mexican-American slang and also in all regions of Mexico used commonly as an exclamation expressing approval or encouragement. The term has varying connotations, including an affirmation that something is impressive, an agreement with a statement (akin to "word") or distress. According to the Brief Dictionary of Mexicanisms found on the web site of the Mexican Academy of the Language, the word’s origin is a shortening of “ahora”, meaning “now”, with the added suffix “-le”, which is a grammatical expletive – a word part that occupies a position without adding to the sense. Compare “ándale” and “épale”.
