Format code tag that literally means "Replace this by a string of characters". Orinigally introduced in the C programming language as a format specifier for the printf function, it was later adopted by a plethora of other languages such as java, ruby, etc.
In C:

name = (char *)"Danny Boy";
printf("Hello '%s'.",name);

Produces;

Hello Danny boy.

Syntax is almost identical in any other language that implements printf.

~S~ is used in chat for online multiplayer combat games for saluting or addressing many people in a room. It means "salute (all)". As opposed to S! for saluting.

It is probable that this originated in Microsoft Combat Flight Simulator and moved up through the years to other games and newer versions such as IL2 or CS.

Short for social anxiety. Social anxiety is a term used to describe an experience of anxiety (emotional discomfort, fear, apprehension or worry) regarding social situations, interactions with other and being evaluated or scruntinized by other people.
A man finds it difficult to walk down the street because he’s self-conscious and feels that people are watching him from their windows. Worse, he may run into a person on the sidewalk and be forced to say hello to them. He’s not sure he can do that. His voice will catch, his "hello" will sound weak, and the other person will know he’s frightened.
