Sorry if I wasn't clear, internally we've been talking about it a lot, but I forgot that it doesn't have such a solid definition outside of our work. Thankfully, we try to define it in section 7.3 of the NLLB paper: https://arxiv.org/pdf/2207.04672.pdf
The tldr is that if you say:
"Thank you for this job offer." you wouldn't want it to be (mis)translated as "Go F*k yourself.". But if you do say "Go F yourself", you still want it to be translated as that.
