Memetic Mutation: Along with the use in American Psycho, an edit of "Hip to Be Square" that changes various lyrics to "Fuck bees" (but primarily "be square") has also gone around (the "fuck" voice clip is from an equally memetic Penn & Teller: Bullshit! clip). This version gained a lot more prominence after it was featured in a particularVinesauce stream; as one YouTube commenter on the official music video put it, the rest of the comments were "either about fucking bees or American Psycho". Put two and two together and, well, this happens.
Narm Charm: Many of the love songs and their videos. ESPECIALLY their videos.
