老美描述一個人的性格，所用的字眼，往往含有一些口語或俚語，似乎顯得「含蓄」、「細膩」，有時也較「簡潔」、「有力」。以下都是道地常用的美語，咱們有時也可派上用場。(例句中的主詞、動詞時態、單複數，都可隨意改變) 這裡我分兩方面來說：

(1)描述較差的品格或習性：

例如：
He constantly berates and belittles his wife for some trivial matter. 他常常為了芝麻小事，痛罵和貶低他的太座。
(berate 痛罵=scold；belittle 貶低，小看)

She is self-centered, deceitful, manipulative, promiscuous and enjoys the chaos and drama caused by her bad choices.
她很自我中心、不老實、善於操縱、行為隨便，喜歡做些雜亂無章戲劇性的不好選擇。
(deceit n.欺騙；promiscuous多指男女亂交；chaos雜亂)

Mr. A always takes his anger out on his wife and children. A先生常常拿他的太太和孩子出氣。
(to take one's anger out on someone拿某人出氣)

I don't believe them; they are up to their old tricks. 我不信任他們；他們在耍他們的老花招。
(to be up to one's tricks耍花招，惡作劇)

All he will do is to put bamboo shoots underneath your nails. 他的所作所為，就是要讓你受苦受罪。
(to put bamboo shoots underneath someone's nails 就是在某人的指甲下插入尖竹；= to torture someone 或 to give someone hard time)

She made herself a laughing stock to those around her. 她把自己成為她周圍人談話的笑柄。
(laughing stock 笑柄)

He is not only a penny-pincher, but also a very judgmental person. 他不但是位吝嗇鬼，也是位喜歡自作評價者。
(judgmental 自作判斷；penny-pincher 小氣鬼)

Mr. A created a circus, a humiliation and the embarrassment of all time.
A先生製造出一場如耍馬戲般的喧鬧場面，整個時間充滿了丟臉和尷尬。
(circus=mess；humiliation 蒙羞；embarrassment 難堪，窘迫)

As he is nasty, his wife is getting cross and downright hateful with him.
由於他很卑鄙難處，他太太開始不高興而且的確討厭他。
(to get cross = to get mad; downright 十足地 = absolutely)

He is insensitive, selfish and often just plain rude. 他是麻木不仁，自私自利，顯然地粗魯無禮。
(insensitive 無感覺的，麻木的；rude粗野的，無禮的)

Being drunk and belligerent, he turned the air (around them) blue with profanity.
他酒醉，好鬥，把周圍的氣氛變成下流不道德。
(blue = blue language下流語言 = profane language; to turn the air blue = to profane the air = to fill the air with profanity)

While I was talking he cut me short, it makes me feel like a freak.
當我說話時，他就插嘴打斷；讓我覺得自己很沒有用。
(to cut someone short 指打斷某人說話，老美認為很不禮貌。freak = useless person)

He is extremely narcissistic and passively aggressive and controlling as well as abusive.
他是非常自我陶醉和過份放肆，同時操縱控制，惡言謾罵。
(narcissist 自我陶醉者；narcissistic 孤芳自賞的；aggressive 帶有侵犯性的)

Mr. B refuses to part with a dime, unless it is for himself; he has always been a tightwad.
B先生除為自己外，不肯花一毛錢；他總是小氣兮兮。
(to part with = to spend; tightwad = penny-pincher = cheapskate吝嗇鬼)

As a heel, he has all kinds of tongue-in-cheek expressions. 他是位粗魯的人，總說許多不三不四的話。
(heel 卑鄙的傢伙；tongue-in-cheek 不可當真的，無誠意的 = not sincerely)

I am perplexed as to why he gave you such hardship. 我很難了解他為什麼給你這樣的難處。
(perplex v. 困惑，弄糊塗)

Her behavior has become exhibitionist and totally out of character.
她的行為變成愛出風頭，跟她正常的性格大不相同。
(exhibitionist 表現狂，當形容詞 = exhibitionistic; out of character = different from normal character)

Judging from her behavior, she seems to be the Wicked Witch of the West.
從她的行為來看，她似乎是位邪惡的女巫。
(wicked 邪惡的； witch 女巫；Wicked Witch of the West = troubled woman 這是專指女人，W都要大寫)

I make no bones about the fact that Mr. C is my least-admired public figure.
我直言不諱，事實上C先生是我最不羨慕的大眾人物。
(to make no bones about = frankly speaking)
