What does 一生やってろ exactly mean?


I’ve seen this phrase being used and it just confuses me. I wanted to see if I
could find an explanation for the phrase.

A direct translation would be something like "Do it for the rest of your
life," but it doesn't really make sense in some contexts. For example, in a
manga, there is a couple out in the open doing the stereotypical "couple"
things. Then a guy walking by will say "一生やってろ！" So I just wanted to know if
there is another way to interpret the phrase.




It's often a verbal irony, in that the speaker means the opposite without
saying it. So the speaker's inner thought could be "I think that's
unproductive/going nowhere, I'd stop it".

In doujin context, it looks like it means something like "[you two are]
hopelessly in love".
