Old Head
An old person who hates today's generation of rap music and thinks their generation of rap music is the best type of music to ever exist. They will constantly bash new generation rappers labeling them as mumble rappers and when you fight back saying "everyone has their own taste, what if I didn't like your generation" they get all defensive and lose their temper.
(Old Head walks up to a group of teens blasting Migos through their speakers)
Old Head: "Turn that shit off! Their lyrics make no sense and it hurts my ears!"
Teen 1: "Sorry, you old virgin, but kids like us actually get invited to parties."
Old Head: "In my day of hip-hop music, lyrics made sense! Goddammit, now we have gay mumble rappers like Lil Uzi Vert and Young Thug wearing dresses and making godawful music!"
Teen 2: "Your parents probably hated your music while you were growing up, they were probably the type to say '2pac and Biggie are BAD role models!' or something. And bro, Uzi and Thugger got their own fashion statements. Once again, I bet when you were our age watching rap music videos your mom would be like: 'Why does everyone dress like a gangster? It's sick!'"
Old Head: "Maybe they did, but that's not the point! The POINT IS THAT YOU ARE LUCKY I DON'T SLAP YOU FOR DISSING 2PAC AND BIGGIE! THEY PAVED THE WAY FOR ALL THESE NEW RAPPERS YOU GODDAMN KIDS LISTEN TO!"
Teen 3: "Yo, calm down. We didn't wanna fuck you up for dissing Migos. Why so defensive? Besides, he didn't even diss 2pac and Biggie, he just said your parents probably didn't like them which was true. And 2pac and Biggie did not pave the way for our generation, Lil Wayne did. Let's bounce, I can't with these old heads."
