>>10824578They're pretty easy to figure out, especially in retrospect.
Mullet = Popular 80s hairstyle that Marty McFly's is *slightly* reminiscent of.
Jam = Music. As in jam session, or "Let's jam."
Waffles = Eggo Waffles, which are famously Eleven's favorite food in Stranger Things.
Soundwave being listed different though? I can only assume because the leaked codenames renders "Trooper" worthless as a codename now since people know what it means.
And Frank (or Franky) is sometimes a shortened nickname for Francis, kinda like Bob is for Robert, or Bill is for William. So Francis = Frank, which itself is short for Frankenstein.
