In the 1967 song "Status Back Baby" by Frank Zappa, some of the lyrics go:
The other night we painted posters
They played some records by the Coasters
BOW WOW WOW WOW!
A bunch of pom-pom girls looked down their nose at me.
They had painted tons of posters; I had painted three.
What does "painting posters" refer to here? Surely they had photo copiers/presses in the late 1960s? They had to "paint" posters manually? I get the mental image of a bunch of jocks and cheerleaders sitting around in a room in their school and manually painting large paper posters with paint, probably related to some kind of event in their school and/or for the community.
Was it like a "social thing" to paint them manually or what? They could have copied them, but that felt too "dead" and maybe cost too much? Am I way off? Is this even what's being referred to? Or is "painting posters" yet another "code phrase" which really just means "making out"? Like "doing homework" apparently meant that as well?
