Mid Night Club 

Very popular Illegal Street racing group in Japanese Sub culture, consisted of truly elite racers not ricers. Entry into the club required a car with a minimum speed of 155 mph as race speeds often exceeded 215mph. Apprenticeship for 1 year was mandatory before becoming a full member. Safety was highy stressed in the Mid Night Club, drivers who showed recklessness and posed a danger would have their membership revoked. Races were carried out on the Bayshore Route of the Shuto Expressway between Tokyo and Yokohama. Quality of the drivers made it nearly impossible to be caught by police.
Membership cars were often very heavily modified, producing up to 600 BHP. As club policy inquiry into how its racers could easily afford such high priced modifications was prohibited.
The group permanently disbanded in 1999, when a fatal accident occured while racing a group of bikers. Several were hospitalised and a person was killed. As club policy, if such a thing happened they would end the club forever.
The Rockstar racing series Midnight Club is based on these actual racers, the two Kanji letters in Midnight Club translate to Wangan, meaning Bayshore, the route raced by the drivers.

Mid-Life Crisis Mobile 

(mid lIf 'krI-s&s 'mo-"bEl)
abbr. MLCM

A Mid-Life Crisis Mobile is traditionally a small, sporty automobile, and most often convertible. Common examples of such an automobile are the Mazda Miata, the Lexus SC430, the Chevrolet SSR, and any of a large number of Italian cars that cost as much as a house. The archetypical owner of a Mid-Life Crisis Mobile is male, 37-50 years old, has hair that is thinning or graying (or both). If there is a passenger, there are two possibilities; a female approximately the same age as the driver (the driver's original wife), or a female in her early to mid 20s with bleached hair and enhanced cleavage (either the driver's mistress or new trophy wife).

Compare to Daddy Bought It Mobile

"Hey Brent, did your dad just get a convertible Mustang? That car is such an MLCM. What's next, fake boobs on your mom?"

Mid-Night Brown 

One of five basic turd colors. A turd with a dark brown color and extremely fudgie consistency. Although this turd can be described as "healthy", it's lack of sufficient bile can cause one to use an excessive amount of toilet paper to properly clean ones butt hole.

This term may also be used to describe the 44th President of the United States.

Also see, Sweet Potatoe Orange, Jet Black, Jungle Green and Rutabaga Red.

I thought I'd never stop wiping that Mid-Night Brown.

The Mid-Night Brown left skid marks on the back of the crapper.

I wish that Mid-Night Brown would be impeached for treason, otherwise we have have to put up with another two years of the asshole.
