A phrase for nerds to put on t-shirts (or a bumper sticker on their computer) so they can snicker about putting one more level of encryption on their rebelliousness that doesn't actually exist. NOTE: converted literally from binary to decimal it means 4:20.
Nerd 1: Hee Hee, my case says 100:10100
Nerd 2: What is 4:20?
Nerd 1: It's a marijuana thing...
Nerd 2: Do you smoke pot?
Nerd 1: That's not the point.
