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.

"sage" is what the friendly community of 4chan usually posts to incline a good thread, basically short for, "OP is a sage/OP is very wise". Other expressions used by the friendly users to the same effect include "win", "epic" or perhaps the most common, "lulz" which is a corruption of the word "lol".
