Only the sickest day of the year which takes place every year on March 11 (3/11). This day commemorates the greatness of the band 311. On this day, people who love this band usually have a huge party, smoke tons of marijuana and have a fucking ill time while listening to their music.
Bato 1: Yo man, guess what this Saturday is!!
Bato 2: Hmm, I dunno what could it be?
Bato 1: Its 311 Day!!!!
Bato 2: Yo holy fuck, lets celebrate.
-I'll bring my bong, some beer, and some chicks.
