I would just like to add that we should try our best not to imitate the Kuffaar. I don't know why people keep referring to each other as "guys and girls" when in fact we are brothers and sisters.
And when people wish to express their laughter, they have to resort to inappropriate abbreviations like "lmao". As a point of interest, some people have developed a more modest version: loq (laughing out quietly) - it might not be perfect but better than using obscene language.

As Muslims, we have been taught excellent manners by our dear Prophet (saw) and are the best nation raised up for mankind. Let us then act accordingly and drop this foolish street slang and instead show politeness and respect in our posts. If we come here to gain knowledge, then we should attain it in the proper manner.

A mere reminder for myself and my dear respected brothers and sisters,
