Invented in 2007 by a group of co-workers from the western Chicago Suburb of Wood Dale, IL, Mustache De Mayo is often abbreviated to "MDM". Mustache De Mayo is a celebration of May 5th by proudly displaying hair on your upper lip for just one day. To achieve the maximum unveiling of the mustache, a full beard or goatee must be grown in advance. Most often than not the MDM participant will create a persona and dress up in a fashion that suits the "stache".

Dude, Bill finally shaved off that my first mustache he's been sporting since the 9th grade. That camaro look is completely shot.

Brock: "Okay, but if you pass out I'll bleach your mustache."

Most cops seem to believe they will get more respect if they grow a "Law Enforcement Mustache." It's a great accessory to wrap-around and/or Top Gun style sunglasses.
When you see the Law Enforcement Mustache, you know to stop playing around.
The Law Enforcement Mustache is not to be confused with the "Football Coach Mustache."
