erray
originated in the bay area.. "erray!" is a friendly greeting. or a way to find someone or call them out to get your attention. like saying "ay!" "hey!" "sups"
if you`re walking down a street in frisco, and you see one of your patnas up the block, you go "erray!" and they look back, and see you. or when you call someone on the phone, they say "hello?" you go "erray!" and they say it too. it`s like saying "wassup".. only left coast style. (:
