As an Adjective: Bitchy
You can call a man or a woman a bitch (with different meanings, as described in 3 and 4), but the word bitchy (applied to both men and women) has the sense of “annoying” or “unpleasant.” For example: You’re being really bitchy today. Why can’t you be nicer to me? This is still not very polite language and would probably be offensive.
作为形容词：Bitchy。你可以称一个男人或女人是 bitch（它有不同的含义，3,4中讲过了），但是单词 bitchy （男女通用）带有“烦人的”或者“令人不愉快”的感觉。例如：你今天真的很让人不高心。你为什么就不能对我好点？这仍然是很不礼貌的说法，并且有可能冒犯到别人。
Bitch as a Verb (Complain)
In this colloquial use of the word, “bitch” means “complain.” It is often used together with “moan” (gemir) to negatively portray someone (or yourself) who is complaining too much. This use is not really offensive (depending on the tone) and can be used informal situations. For example: I wish people would just stop BITCHING AND MOANING about corruption in politics and do something about it.
“bitch”作为动词（抱怨）。“bitch”的这种口语用法表示“抱怨”。它通常和“moan” （抱怨）一起使用，来负面的描述某人（或者是你自己）抱怨太多。这种用法并不真的太冒犯人（取决于语气），并且可以用在非正式场合。例如：我希望人们可以停止哼哼唧唧的抱怨政坛腐败而是做点什么。
Bitch Someone Out
means to yell at someone in a really negative way for something they did. For example: My boss BITCHED ME OUT for being 10 minutes late. To use this expression is not offensive, but language is very colloquial.
Bitch someone out表示因为某人做的事情，非常消极的对他们大喊大叫。例如：我的老板因为我迟到了10分钟就对我大喊大叫（BITCHED ME OUT）。使用这个表达不会很冒犯别人，但是这种说法是非常口语化的。
Bitchin’ as an Adjective
This means that something is good, awesome, cool, etc. Don’t confuse this with bitchy (explained above).For example: The Real Life English party was BITCHIN’! Following the rules of grammar would make this “bitching ” but we say “bitchin.” This is another colloquial expression that isn’t negative.
Bitchin’作为形容词。这个词表示某物很好、很棒、很酷，等等。不要把这个和 bitchy（上面解释过）弄混了。例如：The Real Life 的英语晚会很BITCHIN’（很棒的）！按照语法规则应该是“bitching ”，但是我们说“bitchin”。这是另外一种不带负面色彩的口语化表达。
