to chill yourself the fuck out, to calm yourself down, to quit worrying needlessly. Used primarily by seasonedstoners when dealing with a younger, more inexperienced smoker who is freaking out.

Person 1: "Hey! It's too bad that you won't be able to party with us this weekend!"
Relaxicator: "Can't! My mom is making me visit our relatives that I have never even met before and that's because they all died about 100 years ago. My mom hasn't even met any of them either, but she wants to visit every cemetery she can find with our last name on it. She said, "You are going to have fun, whether you like it or not!", so I'm going to download a horror movie while she looks for the dead among the living!
