"Main" translates to "play" or "playground" in English. "Pantat" means "buttocks" or "bottom." "Budak" means "children" or "kids." "Melayu" refers to "Malay" people or things related to Malaysia. "Sekolah" is "school" or "schooling." "Upd" might be a typo, possibly "updated" or "UPD" from Indonesian, which could mean "latest news" or "update." However, in Malaysian contexts, "UPD" isn't a standard term. Maybe the user meant "update" or "latest information."
