1. To add plaster or a similar substance over a surface in order to make it even. A noun or pronoun can be used between "dub" and "out." You really should have dubbed the wall out before you started painting. You're going to end up with a bumpy texture if you don't dub out the wall before hanging that wallpaper. This wall is a wavy mess. I don't even know that we can dub it out!

2. To add a dubstep beat to a song or remix a song in the style of dubstep. A noun or pronoun can be used between "dub" and "out." I just can't believe someone dubbed out "Bohemian Rhapsody." What sacrilege. The studio wants to dub the track out a bit more. That DJ dubbed out a really good remix of that song. It makes me want to get up and dance!
