The act of completely deleting a post from the internet and all traces that link to it, often for the purpose of hiding personal information, avoiding discourse, or silencing a comment section that has gone too far to ever be corrected naturally.
The act of "nuking"
something can be used in dozens of different contexts alike, most notably as a metaphor for destroying any trace of something left behind so as to get rid of anything that particular
person doesn't wish to spread out further. In the
case of online posts, this can be used as a last resort option to fix the mistakes of which cannot be reversed, only destroyed.
It's important to note that nuking a post only works when all traces of said post are lost
forever. This does not
mean making the post private, only accessible to friends, or publicized elsewhere on the internet. When you
nuke the post, it's gone for good, and it's a saving grace only some can achieve the right way.
