To ask what this phrase means to you?

[WaterBird]

I was once told by a toxic person in my life (with whom I no longer have contact with) to "go fuck myself" and have seen this phrase tossed around on occasion when not relating to me.
I'm wondering how others would interpret this phrase... does it mean "Go hurt/kill yourself" or is it just an expression of anger people use when they want to be rude because they know it sounds nasty?
Thanks.

Just an expression of anger IMO. Like a more extreme 'screw you'

Never thought of it as anything to do with killing/hurting

I wouldn’t over think it. It’s a general “I don’t want anything to do with you, stay away from me” to me.

I’ve not noticed it used as an incitement to harm. I’ve generally always thought of it as a more elaborate version of fuck off.

I’ve never thought of it as go kill yourself or anything remotely like that. It’s just a more aggressive way of saying get lost to me.

It just means fuck off.

They just want you to fuck off.

It's as meaningless as using the adjective 'toxic' that some people have appropriated to mean 'something they don't like'.

As above, it just means fuck off. Nothing to do with hurting or killing.

Thank you guys for setting me straight on what this means.
This person had been very toxic to me and had told me worse, which is why I thought that the phrase and harm were related.

I always took it literally, like, "Go away and amuse yourself with something else, like wanking" but obviously with more anger/hate.

I’ve always understood it just to be a form of ‘fuck off’.

Hope you’re ok, OP.

Thanks. I'm OK.

It’s basically just a stronger way of saying “piss off”

It's a horrible thing to say, just rude. Means 'on yer bike' only more extreme.
