What does @ mean as an emoticon?

The @ symbol is not typically used as a standalone emoticon to convey a specific emotion or facial expression. However, in some contexts, it can be part of a more complex emoticon.

For example, in the list of emoticons on Wikipedia, @;--, @}->--, and similar combinations are used to represent a rose or a flower, rather than a facial expression or emotion23.

In general, the @ symbol itself does not have a widely recognized meaning as an emoticon.
