acronym for Middle Lane Moron: a driver who does not keep to the inside lane unless overtaking on a multi-lane highway, in countries where this rule applies (mostly used in the uk), sticking religiously to the middle lane instead. MLM's cause frustration or even road rage to other drivers who are driving faster (for typical MLM's, this is most drivers), as passing them requires superfluous lane changes and inefficient use of the road (passing on an inside lane, or 'undertaking', is illegal), causing congestion. Also known as members of the MLOC (middle lane owner's club). Related - and even worse - are OLM's (outside lane morons), who stick to the outside lane, as legally passing is impossible.

see also Multi-Level Marketing. A scheme in which a person (as a "seller") buys a certain amount of product from a "distributor", and then sells for a profit. The seller must then kick back some of his profit to his distributor. In turn all the other sellers this person has recruited and distributes product to must kick back some of their profits to him.

Amway is the prototypical MLM. Usually only the founders of a MLM profit from the scheme. Some MLM's are blatant pyramid schemes, although one can argue all MLM's are fraudulent. Look for MLM ads in bus shelters and on telephone poles at intersections.

The computer abbreviation for giving someone "the bird." Most commonly used in Instant Messaging services.
