Slide To The Same
The concept used in this lick is very simple - maybe that is what makes it so effective. Play one note and find the same note on the next string and slide to it.
The blues guys have been using it since day 1. The rock guys and country guys stole it from them. It's everywhere cos it sounds cool. The same note does sound different on different strings and you get all these other slide noises in there that just make it sound cool :)
Really helps if you know the notes all over the fingerboard - if you don't then maybe now is the time to start learning them!
