这里的lol不是游戏里常说的英雄联盟的代名词，而是laugh out loudly 就是大笑的意思，有点像中文的呵呵。在外国的文字聊天方式中比较常用。
外国聊天时常用的聊天缩写:
首字母缩写
由每个单词的第一个字母组合而成的，比如UN就是指United Nations。短信里，首字母缩写常常被用在习惯用语中。另外，发声相似的词会被字母取代。
OIC- Oh I see.
BRB - Be right back
BFN - Bye for now
LOL - Laughing out loud
ASAP - As soon as possible
BTW - By the way
FYI - For your information
JK - Just kidding
TTYL - Talk to you later
Contractions 缩略
短信的缩略词不是指一些约定俗成的"don't" 或 "they're"之类的缩略，但两者的目的是一样的：即当意思很清楚的时候可将一些不需要的词省略。元音常常会被省略，但是你仍然可以保留这个词的大概 发言。数字8有时候会发eight，所以later就写成l8r。数字4通常也被取代成for，就像2这个音就替代了to。
Plz - Please
Thx - Thanks
Cya - See you
L8r - Later
K - OK
U - You
R - Are
B4 - Before
2morro - Tomorrow
asl=age sex 地址 英文聊天开场最常用的对白，三个字母相应的代替了三句话，分别是how old are you? male or female? and where are you from? 一句话，我们的原则是越简单越好。
cuz/cos=because 因为的缩写
2=to 数字代替了字母
u/ya=you 你
howr u/h r u=how are you 你好吗？你怎么样？
me 2=me too 我也是
brb=be right back 一会儿回来的说法
wb=welcome back 当一会儿回来的人回来的时候，枣盯纳你可以说欢迎回来，很礼貌的说法。
sup=what'sup 这个是熟人之间问好的常用形式，就好比中国人见面问“嘛呢?"回答就直接告诉别人你正在忙什么，如果没什么特别的可以回答notmuch/nothing speical，这就是最地道的表达。千万别以为sup就是supper,跟吃一点关系都没有。
uni=university 大学的缩写，在英语中，很多比较长的词都有特殊的缩写，大概美国人比较懒。
gvmt=government 政府的缩写
goodnite/nite=good night晚安
yes/yep/yeah “好”的几种表达
no/nope/nah “不”的几种表达，个人认为总说no太单调，而且也太生硬了，可以试着其它的两种回答
gotdc=got disconnected 聊到一凳没半时，却掉线了，这个时候应该怎么说呢？gotdc是比较简单的表达。还有一种情况，就是电脑突然定住，需要重起，当你再度上线的时候，可以说my pcfroze，我们用"冻"这个词，是比较生动贴切的。
wanna=want to 想要...
gotta=got to 要...样
gonna=going to 要去...
cya/c u=see you 再见的缩写
dunno=don't know 不知道的缩写
kinda=kind of 一种...
prob'ly=probably 很有可能...
lemme=let me 让我...
n=and 和
r=are/our 是
gimme=give me 给我...
yrw=you are welcome 不客气
pvt=private 私人的
lota=lot of 很多
t/c=take care 保重的缩写，聊到最后要离开，说完再见还可以说一句保重，显得很有礼貌。或者，家里的客人要离开，送到门口时常常会说一句保重之类的话，英文的说法就是take care。则乎
favo=favorite 最喜欢的
4=for 为...
b4=before 以前
j/k=justkidding 开玩笑的缩写，也可以说just joking，一般程度的开玩笑就可以说just kidding/justjoking,如果某人说了一件另你感到吃惊的事，你可以反问"you kidding?", 更深程度表达吃惊的用法是"you got to bekidding me?"如果这样说了,那就表示这件事是你做梦都没想到的。
ain't=be not 不是
nvm=never mind 别介意
msg=message 信息
luv=love 爱
bro=brother 兄弟
sis=sister 姐妹
doc=doctor 医生
sorta=sort of 一种...
outa=out of ...之外
O.J.=orange juice桔汁的缩写
thanx=thanks
sms 经常发短信，那么发短信的正确说法是什么呢？可以说send a message,但更简单的说法是sms,你可以说 i will sms you,此外，sms的正确读音是[esmes]。
gtg=gotta go 表示要走了，这句话的用途很广泛，想下线的时候可以这样说，在真实生活中也很常用，聊电话想挂的时候除了说hang up外，也可以说gotta go。
lol=laugh of lot 英文聊天中出现频率最高的几个词之一，其实就是彪悍的笑，如果你不打haha的话，这个lol也可以表示大笑，并且三个字母组合起来的图案就如某人大笑的嘴，很是生动。
