I need to know, is this behavior toxic?

So i just got off a game pretty confused. I like to joke by saying "worth" after dying and not getting anything out of it. Even the enemy laner was playing along like they always do. But yeah, it's all I kept saying in all chat. Is that in any way toxic? because later on, the varus I was against said I was toxic even after he played along for a bit... Of course, i asked why, no reason provided other than that i was remuted. Blitz did say : "to sum it up , you talk too much." Is talking verbal abuse now?

Then, I say "bye bae" to my team mate vlad, after both of us got flanked. Then he tells me to kill myself? I of course, asked why, he said because I was an obnoxious prick who says "bye bae." (I have pics). Then lucian goes onto to agreeing with him. Telling the enemy team i'm toxic. Um hello, did you read vlad's message?

Is there something I'm ignoring here? Were they right about me being toxic? it's pretty much the first time I get an experience of the sort. People playing a long with me usually and what not. What am i missing?
