Dates on Posts (Replacing with Text instead)...

I was able to remove dates from posts, but can I now insert static text/words in the same place (where the old dates were on posts)? I just want to put fun “buzz” words in the place of old dates (on the same exact spot). The buzz words would be simple promotional text to grab attention.

Would it also be possible to put small icons/images in the place of old dates on posts?

Thank you.
