one of the most bullshistic "holidays" ever. Its the 20th day of April and is when a bunch of stoners get high.

its the gayest holiday ever because if you already get high every day then what the point? like celebrating the 4th of july so what is the fucking point of celebrating 4/20

stoner: heyy man tomorows 4/20 im so exited duhhhhhhh

regular person: wait are you high right now?

stoner: yeah duhhhhhhhhhhhhhhhhhhhhhh

regular person: wtf then whats the point? its like opening christmas presents early. its just messes up the whole feeling of the holiday.

stoner: hey look a bee duhhhhhhhhhhhhhhh

4/20 

some say it was bob marlys birth day (rong). others say it was when a group of college students (aka the "waldos")gathered every day at 4:20 to smoke pot. anuther theory is that 4/20 was the date weed became illegal, or it was hitlers birth/death day

"hey man comin over for 4/20"
