I'll start by breaking down "sha po lang". Translating each part: "sha" could be "杀" in Chinese, which means "kill". "Po" might be "破", meaning "break" or "defy". "Lang" could be "郎", which often translates to "boy" or "man". So putting it together, "sha po lang" might be "Killer Break Boy" or something along those lines. Alternatively, it could be a different transliteration altogether, maybe a character name.
