Ma Mum. The sound of that in a local Singaporean lingo would mean 'mum mum'. It is no doubt many of us grew up with that unique expression. Though to those who have never been to Singapore, one would immediately guess this would intend 'Mothers'. But in the popular Singaporean lingo, it just simply implies an invitation 'to eat'. It is of a unique significance to how its name, 'Ma Mum' came about. 

'Ma' to where the delicious traditional local foods are served, and 'Mum' to where people gather, to dine and rest, or for their 'everybody' social activities.
