"Bud bud" is the sound Indians (brown ones not red ones) make when they talk. My mate reckons they also say "ding ding" afterwards, but I don't see it.

When you eat dirt for the first time and leave your family to build a shack in the woods

a person with whom one shares portable music player headphones with.

Anyone of Middle Eastern, Indian/Pakistani origin. Generally refers to those who are arrogant and are a disgrace to their religion and native country (Terrorists, Extremists, Corner Shop owners who charge the earth for everything).

Depending on who you ask: "bud bud" is cultural; a mating call; simple acknowledgement; courtesy; or term for an invader of curry origin. It's a most typical noise that emanates from street shitters having coonversations amongst themselves anywhere at anytime. In overpopulated third world shitties, a singular "bud bud" is routinely uttered by daily street shitters letting fellow bomb hats or passers-by that a curry laden turd may well be making its maiden voyage down their dirt drain or plastic bottle clogged river sewerage system to shit up the indian ocean some more. A more anxious / hasty exclamation of bud bud can be inturdpreted as a cry for toilet paper.
Street shitting matters.

Same as word Sanjay!
