Oy vey (Yiddish: ××± ×°×² â) or oy vey ist mir is a Yiddish phrase expressing dismay or exasperation. Also spelled oy vay, oy veh, or oi vey, and often abbreviated to oy, the expression may be translated as, oh, woe! or woe is me!.Its Hebrew equivalent is oy vavoy.he Latin equivalent is heu, vae! (pronounced, hoi, vai, amongst others); a more standard expression would be o, me miserum, or heu, me miserum. According to Chabad.org, an alternative theory for the origin of the Yiddish expression is that oy stems from Biblical Hebrew, and that vey is its Aramaic equivalent.
