Calling anyone you don't know your healslave would be an INCREDIBLY rude and offensive thing to do out of the blue like that. If someone was just q'ing up into a dungeon and the rando tank puts a target on my head and calls me his healslave at the start of the run...I would be immediately PO'd and I am not a person who cares at all about "bad words" or obscene language in the least. I swear all the time in chat myself. I wouldn't report the dude, but hoo boy would my temperature rise a few ticks right there. If that is your default macro opener for every piece of content you run....you were inevitably going to get reported sooner or later.

I want to believe this is one of those cases where you don't quite understand English slang as much as perhaps you think you do and aren't aware how ridiculously offensive and demeaning you are being with that opening line, whether you think it is a joke or not. It has both racially and sexually offensive overtones to it that would not sit well with most people coming from a total stranger.
