Bubba Share definition Flag A large nasty crap. Consisting of chinese food. Very stinky most likely coming from a fat bitch. Last night at the party betty and mark got drunk, and betty took a bubba on marks chest. Eww, did you see that bubba in the toilet?? Bubba by McRichard May 2, 2007 0 0 Get merch Get the Bubba mug.
