If you want to bark like foreigners, you should do as what I do. To weave a passage with bullshit in your brain rather than inlay some exotic words in your passage. It's quite OK out of some academic reason for you to explain a word that hard to express in Chinese like Nostalgia or what ever. But if you want to show your sense of nobility just because you could talk some bullshit that others cannot understand that you choose to blend English words into Chinese, even simple words like Thank You. Then I could only regard you as a retard among the retard, the most retard of you. Eat shIt you knucklehead.
