tráng miệng

Etymology
From 🇰🇲, in the sense of "cleansing your palate of savor with juicy fruit or sweet dessert".

Verb

 * 1) to have some fruit or dessert after the main meal

Usage notes

 * Despite the dedicated Vietnamese Wikipedia article and bilingual dictionaries, tráng miệng is first and foremost about fruit, not dessert, given how dessert was introduced much later from the West. As a matter of fact, fruit is more accessible for its price than dessert, and is even given out free of charge at certain dining establishments.
