A mix of the words 'relax' and 'Opal'. Used for when Opal Crankshaft relaxes on the couch when she's stressed out or seems sick. She once told her grandson, Nelson, she was our of sorts, but he didn't know what she meant.
Opal: I'm all out of sorts today. This is crazy. I think it's time to Opalax.
Myrtle: What do you mean? Opalax? Now, I know about relaxing. I used to be a massage therapist, you know?
Opal: It's a mix of the words 'relax' with my name. I use it when I stretch out on the couch. You know how us old women are!
Myrtle: That's wild. I never heard of it before. In Aiwa Beach, Hawaii where I'm from we never even think of Opalaxing. We do pineapple massage down there.
Opal: (shocked) Pineapple massage? Myrtle, what are you talking about?
Myrtle: Come on, sweetheart. Just try it. It'll relax you more than you ever thought. (takes crushed pineapple and starts rubbing it on Opal)
Opal: Oh yeah, this is creamy. I'm all Opalaxed now!
