How to say "trash talking"? I was watching a Chinese student play pool against an American, and the American was getting destroyed, but ended up winning in the end by default (Chinese student scratched on the 8 ball).

So the American jokingly said "not even close".

And I was trying to explain to the Chinese student that it was just trash talking, but wasn't sure how to say that.

Bonus question, what would be an equivalent translation of "not even close", in a joking, trash-talking context?
In this case, what the American said was more a 風涼話 (the game was already over)

風涼話
sarcasm; cynical remarks (made after the fact)

As for trash talk:

trash talk
disparaging, taunting, or boastful comments especially between opponents trying to intimidate each other

It is similar to 吹牛皮 (boasting), 耍貧嘴 (babble with cynical words)  or 耍毒舌 (taunting with mean and provocative words)
牙斬斬 ; 狗噏 in Cantonese:

More importantly, the purpose of 'to trash talk' is 'to trash your adversary'
The most accurate translation of 'trash talking' should be: &quot;自我吹擂，貶損對方 &quot; (boast oneself and disparage the other)

It would be '差遠了'
