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.

A universal phrase that can be used in almost any situation. Usually in response to someone overreacting to something, or when someone does something bad.
"Jim: What the fuck are you doing?! Those are my chips!"
"Kevin: Dude. Don't be so mayo."
*Guy falls off of his skateboard*
"Guy watching: Dude. Don't be so mayo."

During brunch at The General Greene, Derek went to the bathroom to whip up some of his own small batch mayo.
