When I was a teenager, I put local punk band bumper stickers all over my car. One was called “Seminal Expulsion” Every time I went to my grandparents house, that bumper sticker would mysteriously be missing. I was friends with the band members so they gave me a huge stack of bumper stickers so could stick one back on every time it got scraped off.
I had all of theses stickers until I was 21. Then I moved to San Franciso for several years and I didn’t own a car until I was in my late 20s. By then, I just lost interest in bumper stickers.
