Primo = barf in a bottle! Hawaiis contribution to the beer drinking world, bottled formaldehyde.
Many moons ago (late 60s early 70s) while stationed at Pearl Harbor, we would hit the strip (King Kamehameha Highway) and in any bar you would pay about $0.65 for a beer or $0.25 for a Primo.
LOL! I wasn't very discriminating back then, but even I knew it was bad!
