420 

A day where people gather to celebrate and consumer cannabis, better known as marijuana. The term derived from a group of teenagers at a high school in San Rafael, California back in 1971, who would meet after school at 4:20 p.m. to smoke marijuana at the Louis Pasteur statue.

Happy 420!!

The origin of the word goes long before it's use in the US for cannabis. 420 is common term in Indian subcontinent used for someone who is a thief/trickster/clever in mischievous way. The word originates by Penal Code of 1860 instituted by the colonial government of British India. Section 420 covers offences relating to cheating and dishonestly.

I am pretty sure someone from Indian subcontinent (pakistan, india, bangladesh), probably students, tricked some American pot smokers into using the word for themselves back in 1960s or 1970s. What else could explain that weird coincidence? In that sense they were "420" (mischievous trickster) who tricked people into using a (bad) Indian slang for themselves

Look, lets tell American pot smokers in our school that they should call themselves "420". (laughs Hehehee )
