What is meant by toxic behaver online?

Well toxic usually means "words and a attitude that can hurt peoples feelings" so anything with curse words is a easy way to start looking at what is toxic. If you use any curse words "against" anyone then that is sometimes considered toxic considering the person. If they hear you cursing others say the dude who is beating you in a match. that's also toxic. especially if you insult them. What i think happened is that one of your "Jokes" must have hurt someone, maybe it's not the first time one of your "jokes" hurt them. People all have differently ways of talking. (personally I dislike it when people insult the one who is doing good or get mad at the one who is failing but doing his best. Curses are abit much for me and i can't really take an insult or even a light jaunt at me at all. I'm abit of a wimp) Maybe you said something, that while you wouldn't consider it harmful, it was considered harmful to them. Things like this happen. If you truly want to know you could try asking the people who called you toxic in the first place... who knows maybe they got butthurt and they are the real toxic ones. But if it really was your fault and you are able to get in touch them maybe you can stop being toxic. Do your best now ok? I wish you luck in any future endeavors.

It's good that you are trying to treat others the way you want to be treated. Honestly, try to find likeminded people who like to joke around and mostly play with them if you can! Try to be considerate of other people's life experiences, too. Just because something does not make you feel bad / would not make you feel bad doesn't mean it isn't really awful for another person to hear. As an example, joking around about someone's dog dying is funny until you run into that guy with a recently dead dog. The same goes for stuff like gender or race or sexuality. It might seem funny to call your straight friends f*g, but there are people who have been torn apart by friends and family hurling that word at them and it might remind them of something really horrible. I'm not saying to walk on glass around people but just try to recognize when someone is genuinely upset and try to apologize for it if you can so you can get back to playing the game and having a good time.  

What is a behaver? If you can explain to me what a behaver is, I might be able to explain why it is toxic.  Did you really mean to ask "what is a toxic behavior"? Now I am beginning to wonder. 

I would assume that perhaps something was said that you didn't mean to say but someone else took offense to it, reported it where it was reviewed by a moderator who took the action.

Sometimes it best not to say anything in the gaming chats because a friend of mine told me how he lost his account with games in it. Better to just focus on the game not the people. 

toxic is basically equivalent to being an asshole

Lets be blunt here,it means you were acting like a prick.Sounds like your "jokes" were actually insults.I'm glad that you say you've learned your lesson.Kindness is actually a pretty easy,and rewarding way to live.

With what you given us here, I'd have to know the extent of your jokes and such to say with more accuracy...since toxic behavior encompasses a lot of things.

Reflect your actions in the past, and see what you had done wrong. People won't just kicked you without a good reason, except they know your attitude first hand.

Joking is OK, but you need to know the right time for it, and not too overboard with it, especially against someone you don't know well.
