Jackie(in various flashbacks about what she said about Fez): He's a bad, poor, sweaty, stinky, crazy, sick, ridiculous, foreign, spazoid weirdo.
While the viewer is led to believe all these words are about Fez, at least one of these words are put outside of their context. For instance, during the flashback when Jackie says "spazoid", she refers to Donna, and not to Fez. In the episode "Mother's Little Helper" where this flashback is from, the dialogue goes like this:
Jackie(to Donna, who just sat on the couch next to her): Don't bump me!
Donna: Don't get in my way.
Jackie: Well, maybe I wouldn't be in your way if you could sit still like a normal person, instead of a vibrating spazoid.
Donna: Really? Well, guess what. You fight like a poor girl.
