Oh, the symbolism. Childish Glover (Donald Gambino?) goes to pick up a woman person, chauffeurs her in his backseat for a while, splits a bag of Cheetos with her, stops the car and makes out with her for a few minutes/hours, then sits in the back as she takes the driver's seat and heads home. There's probably a whole lot of serious stuff about relationships to read into this, about sex and control and manipulation and all that stuff— Oh Donald, you always seemed so gosh-darned upbeat on Community!—but really it's hard to concentrate enough for a close reading with that electro-funk beat thudding in the background.
Just watch the video, the song's pretty good. Though maybe not if the idea of chugging a mouthful of Cheetos dust grosses you out. (And frankly, if it doesn't, what the hell is wrong with you?!?!)
