Can someone tell me what these two acronyms stand for? If anything?

My friend and I casually play Cubecraft after midnight until maybe 3 or 4 in the morning. We randomly see throughout our night, a few people saying the acronym "ttt" or "3rb". Does ANYONE know what any of those acronyms could mean? Every time we ask, the player ignores us as if they never said it at all.

"Ttt" is just a spam of letters.

"3rb" is the phonetic way of saying "Arab". Most people would ask "3rb?" to see if any Arabic players are in the lobby. Hope this helped!
