Placing words at the end of post information

What does one place in the 'subject' field of a post in order to put the desired text at the end of all the post information after post number? There's a bunch of threads on here for so called 'secrets' and triforce asshattery but nothing for the placement of words in post info. I have seen subject text in the middle of info too, so I'm fairly sure it can be done.

Many thanks in advance all

tl;dr - How do you make words AFTER post number in image boards

4chan's BBCode system was custom built only for those who knew about it after meeting in 4chan's secret quarters, and also it was designed to make you and me look like total retards (more than we need to be anyway).
