Hey guys, I'm new, what does sage mean?

IN one of my posts on b like a bunch of people said they were "saging " my thread, what does it mean?  Sage is like a wise  person, so are they saying my thread had some good wisdom? cause it was supposed to be funny not intellectual.

thx for helping me out guys.

sooo...is it when a post is really good and you want to keep it up without bumping and reaching reply limit...or when it's so sucky, you want it to get deleted and not bumped?
