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.

The disco. We go to disco. My body's sweaty from the MDMA inside it. I like to dance with you. You grab my ponytail. It is greasy with Germanic juices that I put inside my hair. Disco, we are the disco. I have a mesh shirt. My leather pants show off my sausage inside it. I grind your body, then we eat ecstasy and have Special K inside of the bathroom. It's a men's bathroom, but no one cares that you come inside because they know that inside it we do lots of drugs. And I will share them if the bouncer lets me go into the bathroom with you, and then we go home. We have efficient sex. And then I realize you're not that hot anymore because I've blown a load and I don't have ecstasy inside of my bloodstream. So I make sandwich. It has hazelnuts, bread, and some jelly that I got from the supermarket. It tastes pretty good, but it probably tastes better because my taste buds have ecstasy inside them. And then I go up to the bathroom, and you're wearing one of my shirts; that isn't cool. You didn't even ask. I met you earlier the evening; you're not my girlfriend, you're just girl that I have sex with. We probably won't do this again because I realize that your hair is frazzled and it probably has extensions. It's not your real hair, and that's kind of gross 'cause who knows where it came from.
