No, 5th of May is when the Mexicans were outnumbered 3 to 1 and the French still manage to lose to them.
I have a Mexican friend and last year we went to this Cinco De Mayo Fiesta. Lot's of food, cars, somewhat makeshift stores, and lots of music. Well he and i were sort of play fighting in the Volleyball court, and these two chicks starting beating the hell out of each other. 10 minutes later the cops came there and started arresting everyone in sight, we was just lucky that we were only about 13 at the time. It was so fucked up the two girls were all bloody and they finally arrested them after arresting like 7 black people and 20 mexicans just standing and watching it. Weird eh?
I was invited to a Cinco De Mayo party. There was going to be tequila and all kinds of Mexican alcohol and food. I said no because I didn't want to get in trouble. :P WHY DID I SAY NO? GAH! I SHOULD"VE SAID YES AND GOT WASTED >: O
