the 6th of May - a special holiday, devoted to nursing hangovers and otherwise dealing with the consequences of Cinco de Mayo
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."

Top Definition
The day after Cinco de Mayo; usually characterized by deadly farts, a killer hangover, and dormir mucho.
I love Cinco de Mayo- Taco Bell, Corona and lime, sombreros, and jammin' to mariachi songs!
I HATE Seis de Mayo- farts that smell like chalupas and a hangover the size of Mexico. It sucks big cojones.
