63DO Share definition Flag Another sneaky attempt at getting a dirty Russian word on a vanity plate past the DMV. In this case, the word is pronounced "b'z-DOH" and means a fart, usually of the SBD kind. Hey, look at the car in front of us, 63DO! Does that mean that the driver farts a lot? 63DO by pentozali November 13, 2010 0 0 Get merch Get the 63DO mug. Buy Now — $32.95 See more merch
