:-] Meaning in Chat or Text Messages Online

:-] is a symbol used in chat or conversation that can have two different meanings, either a smiling blockhead or sarcasm.

When used as a smiling blockhead, it represents a friendly smiling face with blushed cheeks, as the user is happy or excited about something. For example, "I got an A on my exam! :-]"

However, when used as sarcasm, it can mean the opposite of what it appears to be. For instance, "You forgot about our date again? :-]" would mean "I'm not really happy with you, and you should be ashamed of yourself."

In summary, the context in which a person uses the symbol is significant in determining the intended meaning.
