現代美國俚語作為壹種交際工具，是英語語言中豐富多彩的、極富有活力的成分。它服務於社會，以社會為基礎。隨著社會的發展，其中有壹部分俚語由於不再適應社會，不再實用，慢慢地從社會這個大舞臺上退出。而有壹部分仍然活躍，經久不衰，或者慢慢地進入標準語的行列。與此同時，新的俚語會因社會和時代的需要而如雨後春筍般出現，填補其中的空白。1960年文特華斯和弗萊克森主編的《美國俚語詞典》（Dictionary of American Slang）收錄了15,000個俚語詞，據他們估計，其中美國人常用的有2000多個。而到了1961年，瑪裏安韋伯斯特的“THE INTERNATION”在同意前者的詞義的情況下只列出了500多個俚語詞，可見在這壹年之中有如此多的俚語成為了標準語，衍變速度有多快，同時它們留下的空缺又由新的俚語添補上。

Need that meanwhile, new slang will be because of society and times but if bamboo shoots after a spring rain as appear , fill in blank space among them.

But have arrived at 1961 , have listed more than 500 slang only under the "THE of Malian Webster INTERNATION " condition in the meaning of a word agreeing with the former word, It can be seen that the slang having being more like this in this in 1 year has become standard language, evolve how quick be speed , the vacant position that they leave at the same time replenish is listed in from new slang.
語言來自於社會，來自社會大眾。現代美國俚語的發展趨勢是簡潔明了，正是由於其大眾化，俚語的委婉含義在不斷地弱化，普遍性在不斷增強，逐漸地成為大眾語言不可缺少的壹部分。正是因為人們對俚語認識的不斷加深，社會的不斷進步和開放，所以我們相信現代美國俚語有著強大的生命力和美好的前景。
Language comes from in society , comes from masses of society. Modern USA slang developing trend is to clearly understand , to exactly be since the person is popular concisely , tactful slang import is strengthening unceasingly in ceaseless field reduction , universality , becomes the essential masses language part gradually.
