Yadadimean is a Bay Area term for "Ya know what I mean?" or "Ya know what I'm sayin?" But the Bay crammed it all into one dope ass word. This word never sounds right unless spoken by a true bay nigga or niggette.
Ex: "I gets my hustle on day and night playa, yadadimean?"
Ex: "In the Bay we be doin it different yadadimean?"
