What is the rudest thing someone has ever said to you?

My mother in law said many rude things to me in all the years I knew her.

I don't remember

Fanculo puttana!

Can’t remember what the dumbest thing I’ve seen a person done/said but at work, we had caution tape around our building so people don’t enter (because of covid) yet there are some people that cross it despite seeing others wait behind it, thinking they can enter the building.

Told me to drink bleach

Right off the top of my head, I can think of a couple.  My former boss, among many many other things, said she had no problem scheduling me to work every weekend because I had no life anyway.  And a couple years ago someone posted my picture here and quite a few people who I thought were nice called me a whale, pregnant, etc.

I'm sure there are far worse things but those are the first that come to mind. 

Rude, arrogant, etc. 
I've had people tell me to "Speak English" with people who don't, simply because they were nosy and want to hear & understand conversations which quite honestly, don't concern them.

Probably told me to F off. Not that bad really.
