Popular in the Pacific Northwest, Rainier Beer is a brand of beer that features an iconic script "R" prominently on the can.
Although Rainier is now owned by Pabst brewing and is bottled in California, lots of people in the Pacific Northwest still prefer Rainier as the 'local cheap beer,' as it is most certainly a cheap "macrobrew" not a "microbrew."
"Why do you like Rainier Beer so much?"
"Because I grew up stealing cans of Vitamin R out of my dad's fridge. It's always been my favorite cheap brew."
Vitamin R is derived from amphetamine and is the closet pharmalogical equivalent of cocaine.
It is used as both a study aid and a recreational drug. When used recreationally it is typically snorted, with doses ranging from 20-40mgs, Although it is much more addictive when taken this way.
Bob: fuck yeah! Is mad P gonna let us have some of his vitamin Rs?
Bill: hell yeah. Meet up his place about 8, chill for a while, get drunk. Then at 11 we'll snort 30mgs each and head out.
Bob: I'll bring a spliff for the come-down.
Bill: Cool. Remember, no booze after the vitamin R. Just because you're no longer intoxicated doesn't mean you're no longer drunk.
