Part of Midnight Movies.
In this consumer culture parody, professional wrestler "Rowdy" Roddy Piper (R.I.P.) plays an unemployed working stiff who inadvertently finds a pair of sunglasses that allow him to see the world as it truly is. Billboards carry subliminal messages such as "Submit to Authority," and yuppies are actually aliens who are bent on subduing the human race. Before you can say "Die, yuppie scum!" Piper grabs a gun and starts blasting.
