People on gaming platforms who think it's cool to put 420 in their name. It also applies to anyone with weed related names.
"Look at that guy right there! His name is sUpAkUsH420. I'm pretty sure he thinks he's cool because he smokes weed."

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 number silly, little teenagers talk about for days upon days, but do not get high when April twentieth is finally here.

April twentieth is also Adolf Hitler's birthday. This day is not commonly known as "420" when referred to Hitler's birthday, though.

There is belief that "420" is the police code for a "drug bust," but it is not. There are no codes for a "drug bust," only "drug deal," which is code "966."
