I have collected the most important ones in the table below.
The Internet has always been a source of technology inspired slang.
Here are the three most common smileys: :-) :) ;-) (To see the smiling faces, tilt your head sideways to the left.
Notice that the last smiley is winking.) Use a smiley whenever you think you have said something that the other person might find offensive.
Today, hashtags are used widely outside the Twitter environment.
You will often see them used by people to inject short comments into a conversation.
Hashtags originated on Twitter, where they were first used to create "groupings", that is, to mark a tweet with a certain code, for example #politics.
Chat slang is a method of typing long words and phrases as short one-to-four letter words and is also used by people who have difficulties spelling.
The name comes from the # character, a hash mark or hash.
You will also see this character referred to as "number" (number sign) or "pound" (pound sign).
For example, you will generally see Objoke only in Usenet humor groups (where a person posting a message has included an "obligatory joke"), while BRB would be used when two people are chatting and one tells the other he must leave for a moment, but will "be right back".
If you are a beginner, don't worry about the nuances — it won't take long to catch on.
