A couple consisting of one asian and one caucasian. One part rice (asian) one part cracker (white) equals ricecracker. Can refer to gay or straight couples.
Asked how we decribe gay asian and white couples, I coined the term, as I consider myself to be a cracker, and not a rice queen. Ricecracker summed up me and my partner's relationship quite nicely. Also can be referred to as "ricecracker couple."
An Asian guy (usually Chinese), who smokes crack because he can't afford opium.
The term was most likely coined during the Opium Wars, during which the corrupt Chinese Government imported opium to feed it's own people. Those in power, made huge profits. Those who couldn't afford, turned to crack. Hence rice cracker was born.
My Friend: Gee, your Uncle Chong is such a Rice cracker!
Me: He's going to be rich soon, he's upgrading to Opium!
