stupid drug related slang originating from a bunch of kids who used to get high and look for a field of marijuana way the fuck back in the 70s. for some reason it has perpetuated itself to the point where every dumbass who doesn't know fuck all about drugs adores it, while the left are wondering what the fuck is wrong with everybody
retard: oh my god it's almost 420!

smoker: 4/20 is bullshit. nobody who's really into drugs actually cares about it

retard: well then you must not smoke, because i know everything about drugs. i smoke purple haze and i planted hydro seeds in my yard

1) It was mistakenly reported that there were 420 atoms in one molecule of the tetrahydrocannabinol, and later found to be incorrect, but not until the drug culture had adopted the number as a code for marijuana.
