Uno De Juno 

The holiest of holy days, Uno de Juno was originally a holiday created for non-mexican Spanish speakers. Sick of people assuming since they spoke Spanish that they wanted to celebrate the Mexican holiday of Cinco de Mayo, some Puerto Ricans and their white compatriots in New Orleans adopted Uno de Juno as their own day of holy celebration.

Intentionally misspelled, the first and only rule of Uno de Juno is that it is not celebrated on June 1st and the celebration usually consists of heavy drinking, drug taking and party-goers wearing poorly designed t-shirts.

Everyone got blackout drunk and Sam pissed himself, another great Uno de Juno was had by all.
