翻譯
Translated from Chinglish. If you can do it then you should go up and do it. It's used against people who criticize others' work, especially when the criticizer is not that much better. Often followed by "no can no BB", which means "if you can't do it then don't even criticize it".
中式英語翻譯而來。如果你行，你就應該去做這件事。這句話用來諷刺那些挑剔別人工作的人，尤其是那些自己本身也做不好的人。通常這句話後會跟著“不行別逼逼”，意思是“如果你做不了，就不要挑別人的刺”。
【例句】
"That person does not deserve the award."
“那個人不應該得獎的。”
"You can you up, no can no BB"
“你行你上啊！”
