衮烫的白开水
[gŭn tàng de bái kāi shuĭ]
'衮烫' usually refers to scalding hot liquid and '白开水' refers to plain boiled water. Taken literally, it's like calling oneself 'hot boiling water'. However in the Chinese cultural background this implies simplicity and purity, yet possessing warmth. Just like warm water helps to nourish and soothe, the named person is indicating that they themselves want to have the effect - being simple but helpful.
