The 1975 sheet music

Hey, listen up, numbskull. This meme is all about the sheet music for the band The 1975, but instead of regular notes, it has some rather sus words on it, which are both musical terms. "Cum" is "with" in Italian and “pp” stands for “pianissimo” which means “very quiet”. Now, someone clearly thinks they're being edgy by writing that "pp" is "very hard." Do I have to explain everything to you, you uncultured swine?
