"Seis de Mayo sucks ass"

“Seis de Mayo sucks ass”” (or simply “Happy Seis de Mayo”) is a jocular saying about the day after Cinco de Mayo (May 5th) that has been printed on many images. “Reputed to be a cure for hangovers, it (menudo—ed.) is especially popular on the seis de Mayo” was printed in the Morning Call (Allentown, PA) on April 30, 1986.

“Happy cinco de mayo. Seis de Mayo = No bueno” was posted on Twitter by Tony Bojorquez on May 5, 2007. “Happy Cinco de Mayo…err…happy Seis de Mayo!” was posted on Twitter by Jordan Snyder on May 6, 2008.

“The party is over…seis de mayo sucks” was posted on Twitter by Foxysofa on May 6, 2009. “Seis de mayo sucks!” was posted on Twitter by Micah Walter on May 6, 2009. “Seis de mayo sucks ass” was posted on Twitter by Kelso on May 6, 2012.

“Cinco de Mayo is Spanish for ‘Fifth of May.’ Seis de Mayo is Spanish for ‘I’m never drinking again.’ @JimmyFallon see you tomorrow!” was posted on Twitter by Cassondra Zaleski on May 5, 2010. The line was said that night on television’s The Tonight Show Starring Jimmy Fallon.

“The only downside to Cinco de Mayo is Seis de Hangover” is another saying about May 6th.

Wikipedia: Cinco de Mayo
Cinco de Mayo (pronounced [ˈsiŋko ðe ˈmaʝo] in Latin America, Spanish for “Fifth of May”) is an annual celebration held on May 5. The date is observed to commemorate the Mexican Army’s victory over the French Empire at the Battle of Puebla, on May 5, 1862, under the leadership of General Ignacio Zaragoza. The victory of the smaller Mexican force against a larger French force was a boost to morale for the Mexicans. A year after the battle, a larger French force defeated Zaragoza at the Second Battle of Puebla, and Mexico City soon fell to the invaders.

In the United States, Cinco de Mayo has taken on a significance beyond that in Mexico. More popularly celebrated in the United States than Mexico, the date has become associated with the celebration of Mexican-American culture.

30 April 1986, Morning Call (Allentown, PA), “A Fiesta of Grande Appetites: Mexico’s Cinco de Mayo is a holiday fueled by lively cuisine food” by Pat Strauss, pg. D1:
And for those who lift too many snifters, there’s always menudo. A thick soup made from beef shanks, honeycomb beef tripe, hominy and chile puree, it is served with an assortment of condiments. Reputed to be a cure for hangovers, it is especially popular on the seis de Mayo.
