"Fok" is an all-encompassing expression to meme/make fun of the inevitable presence of toxicity in itself, in online gaming and internet culture, and the typical maturity level of those involved. It can be used as a reminder of this, for the sole purpose of having a laugh, or in case of silence in a chatroom (to contribute something useful). As it is to meme toxicity, it's often used by the rare, more mature and correct users, to have a laugh based on other's inclinations at that moment in time or generally speaking.
It can also improve outcomes, by simplifying every nasty thing that one had to say to the other, with the mighty, all-encompassing expression: "Fok." - it carries a thousand words of resentment, mother insults and more, all in 1 word. Therefore, it becomes more something to laugh about and be less specifically upset over the conflict, infantile insult or "joke" at hand. It can replace more linguistically complex insults.
Because "Fok" is a wonderful shortcut to all the nasty things you'd have liked to say, and otherwise to make fun of the impeding conflict that would otherwise have occured, or more specifically and mainly, to make fun of (meme) the presence of toxicity and toxic inner feels -- it is the solution to everything, to all negative or feelings of social excitation & frustration. All you have to say is 'Fok', and you can rest at ease. Fok is the solution, fok is life. Be a part of the Fok religion.
The birthplace of FOK is frp, in MTA SA.
