Hello Dovie
”tease“, "make fun of", "laugh at" and "play a joke on"?
In regard to your question, let me introduce some words to you.
Benevolent = good intentions
Malevolent = bad intentions
Of the terms you show here, none is specifically Malevolent or "mean" or "mean spirited" but all of them could be. It depends on the context.
"This question is about you PLAYING A JOKE ON US, right?"----[That is an example of me "teasing" you; but from the explicit context, you cannot really know if Bruce is making a friendly remark, or an unfriendly remark.
If I say, "you are PLAYING A JOKE ON US," or
"you are LAUGHING AT us" or
"you are TEASING us" or
"you are MAKING FUN OF us";
Each of these could be spoken or written by Bruce, in a cold, mocking, brutally sarcastic way. It could also be that Bruce is using these expressions in a humorous, friendly, gentle form of joking, or "kidding---around" with you in a loving way.
