土味情话
Tǔ wèi qínghuà
It is often used to describe by those who are disgusted or cringe after hearing something horribly romantic
To breakdown the phrase:
土 means earthly but it can also refer to 'dull' when used in a particular context
味 means flavour. It is commonly used when describing cuisines but in this case, it can mean a distasteful feeling
情 means romance or feelings
话 means words or language
So if you put it together, it is meant to express the dull/cringy feeling towards something extremely romantic.
