Drinko de Mayo is the great Mexican holiday which falls during the month of May. This holliday is not held to any schedule like the ever so regulated "Cinco de Mayo", or May 5th in our native English tongue. Drinko de Mayo is the holiday that celebrates the consumption of copius amounts of Tequila, by men women and children alike. This holiday is often attended by college students on or around finals, and wearing a sombrero is not required, but is generally preferred.
Finals??? On Drinko de Mayo??? WTF man?!
"Are you guys going out tonight?"
"Hells yeah, I got a handle of Cuervo, its Drinko de Mayo, Baby!!!!"

Tom: "Hey Dave, why didn't you show up for work yesterday?"
Dave: "It was May 6th, remember?"
Tom: "Duuude, you were so wasted on Cinco de Mayo- you downed like a full bottle of tequila! That must've been a killer hangover!"
Dave: "That's what why we have Seis de Mayo and aspirin."

Cinco means five and de Mayo stands for "better take a cab home gringo" because 5 times the cervesa means 10 times the hangover bro.
All beers are for a nickel, so while the mahi-mahi mango chutney tacos are good, ayeeeee! Cinco de Mayo is really turning into amatur drinking night isn't it?
