Malay land
Nowadays, due to that 1957 Malaya Federation moment, the Malay people in Malay Peninsula ( 'Kra Peninsula' or 'Malacca Peninsula') tend to associate the term Malay land ( 'tanah Melayu') with Malaysia, while in fact this usage isn't correct and can't be used for Malaysia since it's actually a term referred to the Sumatra island (modern-day part of Indonesia).
