The word is a little old-fashioned and a little humorous; you can say it with a smile, as if the bad temper has become the person’s character. It names the person, not one bad afternoon.

The word這個字is a little old-fashioned有點老派、and又a little humorous有點幽默；you can say it with a smile可以帶著笑容說出口，as if the bad temper has become the person's character好像壞脾氣已經變成這個人的性格。It names the person它說的是這個人本身，not one bad afternoon而不是某一次心情不好的下午。

It is unkind as a direct label to someone’s face, but it is common in stories and in talk about “the old curmudgeon next door.” It is informal-literary rather than slang: you will see it in books and newspaper colour more than in playground speech.

as a direct label to someone's face當面這樣叫一個人、It is unkind這樣講不太客氣，but it is common in stories但在故事裡很常見、and in talk about 'the old curmudgeon next door'也常出現在「隔壁那個老怪脾氣」這種說法裡。It is informal-literary rather than slang它比較偏文學口語、不是俚語：you will see it in books and newspaper colour more than in playground speech比較會出現在書本和報紙的生動描寫裡，而不是操場上的講話。
